3. Discuss the effects of deforestation on the following.

(a) Wild animals

(b) Environment

(d) Cities (Urban areas)

(f) The next generation

(a) Effects of deforestation on wild animals

Removal of trees and plant life from a particular area for the construction of industries, agriculture or for other such purposes is termed Deforestation. Plant life forms an integral part of the ecosystem, and they form the natural habitat of various animals in an ecosystem. Destroying plant life will ultimately threaten the existence of animals in a particular ecosystem and may lead to their extinction.

(b) Effects of deforestation on the environment

In plants, Photosynthesis takes place through the absorption of CO 2 from the earth’s atmosphere. The percentage of CO 2 in the atmosphere increases rapidly if the plant life of an area is destroyed. Increased concentrations of CO 2 result in the trapping of excessive heat radiations within the Earth’s atmosphere contributing to global warming. This results in the rise of the temperature of the Earth and disturbs the water cycle which occurs in nature. Hence, rainfall pattern changes, leading to droughts and floods.

The soil particles are held together in a place by the roots of the plants, trees and other vegetation. In the event of water flow or a high-speed wind over the top layer of the soil, the soil particles get removed easily as there are no plants to hold them in place. Lately, soil erosion has increased by deforestation activities. Soil loses fertility and humus. Hence, fertile land fit for agriculture turns into a desert.

(d) Effects of deforestation on cities

The risk of natural calamities like floods and drought in urban areas has increased by deforestation. It will also lead to global warming because of increased CO 2 levels in the atmosphere. Global warming is a result of continuous pollution from automobiles and industries. The water cycle in the vicinity is also affected.

(e) Effects of deforestation on Earth

Deforestation leads to increased chances and occurrences of desertification, droughts and floods. Carbon Dioxide level in the earth’s atmosphere also increases, which leads to global warming. The water cycle is disrupted, and there is also an increased risk of natural calamities.

(f) Effects of deforestation on the next generation

Our environment is slowly changing due to the activities of deforestation, both directly and indirectly. Soil erosion, global warming, desertification, drought, greenhouse effect, floods and many other problems are caused only because of deforestation. Ultimately, the next generation will face the consequences of deforestation.

4. What will happen if

(a) we go on cutting trees

(b) the habitat of an animal is disturbed

(a) If we go on cutting the trees

If we go on cutting the trees, the animals will lose their natural habitat as an essential part of their ecosystem is destroyed. This reduces the biodiversity of the affected areas. The temperature of the Earth also increases and paves the way to global warming. Global warming, in turn, affects the water cycle. Hence, rainfall pattern changes, leading to droughts and floods. As a result, risks of soil erosion, global warming, desertification, greenhouse effect increase.

(b) If the habitat of an animal is disturbed

All the basic necessities for an animal, like food, water, shelter and protection, are provided by the habitat in which the animal lives-in. Disturbing the habitat of the animals forces them to move to another place in search of food, water, shelter and protection. The animals, in due course, may get killed by other animals.

Removing the top layer of the soil gradually exposes the lower layers of the soil. The lower layers of the soil are hard and rocky in nature and are less fertile. This is because of the reduced quantity of humus. Soil erosion on a continued basis will turn land barren and infertile.

5. Answer in brief.

(a) Why should we conserve biodiversity?

(b) Protected forests are also not completely safe for wild animals. Why?

(d) What are the causes and consequences of deforestation?

(e) What is Red Data Book?

(f) What do you understand by the term migration?

(a) The number and variety of various life forms, such as plants, animals and microorganisms in the area, are called Biodiversity. Both plants and animals have a mutual dependence on each other for their survival. As they are related to one another, the destruction of one will automatically destroy the other. Hence, biodiversity has to be conserved in order to maintain nature’s balance.

(b) People who live near the forests depend on the resources of the forests in order to fulfil their day-to-day needs. Therefore, it is not safe for animals living in protected forests. The animals would be threatened by the presence of the human population. This results in the killing of wild animals and selling their products for huge sums of money.

(c) The forests provide food and other resources to the tribal people. It is inevitable for them to depend on forests and their resources for everyday needs.

(d) Causes of deforestation

There are a lot of causes of deforestation. A few of them are listed below.

I. In order to accommodate the ever-expanding urban population, forest areas are often cleared and converted into lands for various uses.

II. For agricultural activities, like crop cultivation and cattle grazing, forest lands are cleared.

III. Firewood is a major product from the forests, and it is one of the main reasons for cutting trees on a large scale.

Consequences of deforestation

There are a lot of fatal consequences caused by deforestation. A few of them are listed below.

Soil erosion
Loss of biodiversity
Global warming as a result of climate change
Disruption of the water cycle

(e) The Red Data Book is a sourcebook which has an international list of all plant and animal species which are endangered, that is, on the verge of extinction. The International Union for Conservation of Nature and Natural resources (IUCN) maintains the books and adds/removes the names of the species by conducting a comprehensive survey.

(f) The movement of an organism or a group of organisms from its natural habitat to another place on a standard basis at a particular time each and every year is known as migration. The organisms do so in order to avoid uninhabitable conditions of climate or for the process of breeding.

6. In order to meet the ever-increasing demand in factories and for shelter, trees are continually being cut. Is it justified to cut trees for such projects? Discuss and prepare a brief report.

No. Cutting trees in order to meet the ever-growing demands of the human population is not at all justified. There are a vast number of organisms, like wild animals, insects, and birds, living in the forests. The forests provide good-quality air for animals, birds, humans and other organisms. This is because of the process of plant respiration by which they consume harmful carbon dioxide and give out good quality Oxygen. Thus, they keep greenhouse gases and global warming under check. The roots of the flora of the forests help in preventing soil erosion. Natural Calamities such as floods and droughts could also be prevented by their presence. They help in increasing the soil’s fertility and conserving the biodiversity of the ecosystem.

Overutilisation of forests and their resources by cutting a large number of trees in order to satisfy the demands of the ever-increasing human population leads to many long-term problems like

Greenhouse effect
Global warming

Besides the above-listed problems, the effects of large-scale deforestation will leave an everlasting mark on the face of human civilisation. The balance of nature is disturbed by the destruction of trees. Hence, it is of utmost priority and importance to conserve forests.

7. How can you contribute to the maintenance of the green wealth of your locality? Make a list of actions to be taken by you.

I can take care of the green wealth of my locality by growing plants in my locality. I shall motivate the people of my neighbourhood to plant more trees and take care of the existing trees by creating awareness about the importance of plant life in an ecosystem. In order to make this possible, I would initiate the proceedings and organise weekly events on the same. Creating awareness among the children and youth would be of top priority as they will easily understand the issues that we are facing. Planting new trees is as important as looking after the existing ones. So, my volunteers and I would water the plants and trees on a regular basis.

8. Explain how deforestation leads to reduced rainfall.

Removal of trees and plant life from a particular area for the construction of industries, agriculture and other purposes is termed Deforestation. Photosynthesis, in plant life, takes place through the absorption of CO 2 from the earth’s atmosphere. When plant life is destroyed, the Carbon Dioxide levels in the atmosphere will increase drastically, leading to the trap of heat radiation which causes global warming. This rise in temperature will affect the water cycle. Disturbance in the water cycle will lead to a chain of events, and in the end, the rainfall pattern changes and results in droughts.

9. Find out about national parks in your state. Identify and show their location on the outline map of India.

Periyar National Park, located in the state of Kerala.

10. Why should the paper be saved? Prepare a list of ways by which you can save paper.

If one ton of clean white paper is to be produced, seventeen full-grown trees are cut down. Trees play a major role in maintaining a balance in nature. So, it is essential to save paper in order to protect the trees and avoid the impact of the loss of trees on the living organisms that depend on these trees.

Ways to save paper are

Collection and recycling of used paper.
Using both sides of a paper for writing.
Spreading awareness about the importance of paper among school children and youth.
Intelligent and proper use of paper.

11. Complete the word puzzle.

1. Species on the verge of extinction.

2. A book carrying information about endangered species.

5. Consequences of deforestation.

1. Species which have vanished.

3. Species found only in a particular habitat.

4. Variety of plants, animals and microorganisms found in an area.

Frequently Asked Questions on Chapter 7 Conservation of Plants and Animals

Why should we conserve biodiversity.

The number and variety of various life forms, such as plants, animals and microorganisms, in an area are called Biodiversity. Both plants and animals have a mutual dependence on each other for their survival. As they are related to one another, the destruction of one will automatically destroy the other. Hence, biodiversity has to be conserved in order to maintain nature’s balance.

What is Red Data Book?

The Red Data Book is a sourcebook which has an international list of all plant and animal species which are endangered, that is, on the verge of extinction. The International Union for Conservation of Nature (IUCN) maintains the books and adds/removes the names of the species by conducting a comprehensive survey.

How to solve the questions from Chapter 7 of NCERT Solutions for Class 8 Science effortlessly?

What are the topics discussed in chapter 7 of ncert solutions for class 8 science, why should students refer to byju’s ncert solutions for class 8 science chapter 7, what are the causes and consequences of deforestation.

In order to accommodate the ever-expanding urban population, forest areas are often cleared and converted into lands for various uses.
For agricultural activities like crop cultivation and cattle grazing, forest lands are cleared.
Firewood is a major product from the forests, and it is one of the main reasons for cutting trees on a large scale.

What will happen if we go on cutting trees?

If we go on cutting trees, animals will lose their natural habitat as an essential part of their ecosystem is destroyed. This reduces the biodiversity of the affected areas. The temperature of the Earth also increases and paves the way to global warming. Global warming, in turn, affects the water cycle. Eventually, rainfall pattern changes, leading to droughts and floods. Risks of soil erosion, global warming, desertification, and the greenhouse effect increase.

What will happen if the top layer of soil is exposed?

How does deforestation lead to reduced rainfall.

Removal of trees and plant life from a particular area for the construction of industries, agriculture and other purposes is termed Deforestation. Photosynthesis, in plant life, takes place through the absorption of CO2 from the earth’s atmosphere. When plant life is destroyed, the Carbon Dioxide levels in the atmosphere will increase drastically, leading to the trapping of heat radiations which causes global warming. This rise in temperature will affect the water cycle. Disturbance in the water cycle will lead to a chain of events, and in the end, the rainfall pattern changes and results in droughts.

2. Differentiate between the following.

(a) Wildlife sanctuary and Biosphere Reserve

Ans: The difference between wildlife sanctuary and biosphere reserve is given below

Wildlife Sanctuary	Biosphere Reserve
It is a protected region where animals are safeguarded from potential threats such as slaughter. In this location, their ecosystem is generally protected.	It is a big protected area set aside for biodiversity conservation.
It gives wild creatures protection and proper living conditions.	It aids in the preservation of a variety of living things, including plants, animals, and microorganisms.
Gir is a natural sanctuary dedicated to the conservation of Asiatic lions.	The biosphere reserve of Pachmarhi is a well-known biosphere reserve.

(b) Zoo and Wildlife Sanctuary

Ans: The difference between zoo and wildlife sanctuary is given below

Zoo	Wildlife Sanctuary
It is a place where animals are maintained for public display.	It is a protected region where animals are shielded from potential threats such as hunting. In this area, their environment is likewise protected.
It is a man-made habitat.	It protects animals' natural habitats.
Animals are kept in cages, and their feeding and reproduction are regulated.	They are free to travel around, and their feeding and reproduction are not regulated.

3. Discuss the effects of deforestation on the following.

(a) Wild animals

Ans: Effects of deforestation on wild animals:

The destruction of trees or other vegetation from an area for industrial, agricultural, or other uses is known as deforestation. Many animals' habitats are made up of trees and other vegetation. As a result, if wild animal habitat is lost, their numbers will naturally drop.

(b) Environment

Ans: Effects of Deforestation on the Environment:

Photosynthesis occurs when plants absorb CO2 from the atmosphere. The level of CO2 in the atmosphere will rise if plants are killed. As a result, more heat radiation will be trapped by CO2, contributing to global warming. The natural water cycle will be disrupted if the Earth's temperature rises. As a result, there will be a shift in the pattern of rainfall. This could result in flooding or other disasters.

Ans: Effects of Deforestation on Villages:

The main source of revenue in the village is farming, which requires fertile soil. The trees are the ones who keep the soil fruitful by holding on to it. Without trees, the soil will become loose and readily swept away by the wind, and water will cause erosion, reducing the land's productivity. As a result, deforestation will have an impact on the villagers' livelihood.

(d) Cities (Urban areas)

Ans: Effects of Deforestation on Cities:

Because the amount of pollution in cities will be high, as will the level of CO2, trees will be required to clean up the pollutants and give fresh air. However, deforestation will result in a rise in pollution, particularly CO2 emissions from automobiles and industrial waste. It may also raise the temperature in the area, disrupting the water cycle.

Ans: Effects of deforestation on the Earth:

From a bird's eye view, if the number of forests decreases day by day, this will result in an increase in CO2 levels in the air, which will cause global warming by raising the temperature, causing polar ice to melt and sea levels to rise, potentially causing natural disasters. All of this is due to deforestation.

(f) The Next Generation

Ans: Imagine the impact that deforestation will have on the following generation, as we have witnessed the effects of deforestation on a worldwide scale. The likelihood of global warming, soil erosion, greenhouse effect, drought, and flood increases as the number of trees decreases day by day. As a result, these are the other issues that the next generation will confront.

4. What will happen if:

(a) We go on cutting trees.

Ans: If we continue to cut down trees indefinitely, the trees will eventually vanish from the face of the earth. Animals and birds will be displaced from their natural environment. Biodiversity will be extinct. The water cycle has been thrown off. The rainfall pattern has been thrown off. There are floods and droughts to be seen. Soil degradation, desertification, and natural disasters will all become more common.

(b) The habitat of an animal is disturbed.

Ans: When an animal's habitat is damaged, it loses access to basic necessities such as food, shelter, and protection. Creatures will murder other animals for sustenance, putting the survival of the fittest hypothesis into effect. Both vegetation and animals will dwindle in the end.

Ans: If the top layer of the soil is exposed, the nourishing lower layer of the soil, which is hard and rocky in character, will gradually open. Continuous soil erosion depletes the humus content of the soil, rendering it barren and unproductive.

5. Answer in brief:

(a) Why should we conserve biodiversity?

Ans: Plants and animals, as well as microorganisms, make up biodiversity. We all know that all living things are dependent on one another in some way. For example, food, nutrients, and shelter. As a result, if one of the pieces is impacted, the other two will be affected as well. To maintain biodiversity, all of its components must be cultivated and cared for.

(b) Protected forests are also not completely safe for wild animals. Why?

Ans: People who live near protected woods use the resources for their own needs, so the forests are not fully safe for wild animals. They murder animals for personal gain and sell the resulting products for a profit.

Ans: Forests provide food, fodder, and fallen tree branches for tribals. As a result, people rely on wood for their everyday needs.

(d) What are the causes and consequences of deforestation?

Ans: Deforestation occurs for a variety of reasons.

i. Forests are destroyed to accommodate developing urban centers and meet their ever-increasing needs.

ii. Forests are cut down to make way for crops and livestock grazing.

iii. Trees are felled for use as firewood.

Deforestation has the following consequences:

i. Soil erosion

ii. Biodiversity loss

iii. Floods and droughts

iv. Climate change as a result of global warming

v. Water cycle disruption

(e) What is a Red Data Book?

Ans: The Red Data Book is a reference book that keeps track of all endangered animal and plant species around the world. The International Union for Conservation of Nature (IUCN) maintains this database (International Union for Conservation of Nature and Natural resources).

(f) What do you understand by the term migration?

Ans: The movement of an organism or a group of organisms from one place to another at a specific time each year is referred to as migration. Organisms move from one location to another to avoid harsh climatic circumstances or to reproduce.

6. In order to meet the ever-increasing demand in factories and for shelter, trees are being continually cut. Is it justified to cut trees for such projects? Discuss and prepare a brief report.

Ans: No, chopping down trees to meet the needs of the human population is not justified. Trees provide a home for a wide range of animals and microbes. They give off O2 and absorb dangerous CO2 gas from the atmosphere, providing us with high-quality air. They protect against soil erosion as well as other natural calamities such as floods. They aid in the fertility of the soil and protect the planet from global warming, or the greenhouse effect, which is caused by people. The removal of forests will upset the natural balance. As a result, tree cutting for personal benefit should be prohibited, and forests should be preserved.

7. How can you contribute to the maintenance of the green wealth of your locality? Make a list of actions to be taken by you.

Ans: To begin, one should take care of the plants and trees that are already flourishing in the area in order to contribute to society's green wealth. Later, you can take action by planting more trees in the area. After that, one can begin to raise awareness among the general public and explain the significance to them. The tagline for the campaigns should be "each one plant one," and more trees should be planted and grown.

8. Explain how deforestation leads to reduced rainfall.

Ans: Deforestation refers to the removal of plants and other trees from the environment for industrial, agricultural, or human interests. Trees regulate the CO 2 and O 2 levels in the atmosphere and safeguard the planet from global warming. It also aids in the preservation of the earth's water cycle. Deforestation has the potential to disrupt the water cycle, raise global temperatures, and alter rainfall patterns. It can also cause draughts in certain areas.

9. Find out about national parks in your state. Identify and show their location on the outline map of India.

Ans: The Corbett National Park is one of the national parks near Delhi.

10. Why should the paper be saved? Prepare a list of ways by which you can save paper.

Ans: Paper is made from trees, as we all know. A tonne of paper requires seventeen fully grown trees. We also know that trees help to maintain the natural balance. As a result, we should conserve paper, which will save trees and, as a result, our ecosystem.

Paper can be saved by:

decreasing the amount of paper used.

using both sides of the paper

recycling paper

raising awareness about the dangers of misusing it

11. Complete the world puzzle.
