NCERT Solutions for Class 8 Science Chapter 7: Conservation of Plants and Animals
NCERT Solutions for Class 8 Science Chapter 7 Conservation of Plants and Animals: The chapter begins by telling us about deforestation and the reasons behind it, and it goes on to tell us about the consequences of deforestation and its harmful effects. We read about conservation of wildlife, and different wildlife sanctuaries, national parks, and biosphere reserves in India. We also learn about flora and fauna and their different species found globally, especially in India. The chapter also tells us about migration. It concludes by telling us about the recycling of paper and reforestation as a means to curb the effects of deforestation.
- Deforestation means cutting down trees on a mass scale.
- Deforestation is done to achieve different purposes, as given in the chapter.
- We also learn about the harmful effects of deforestation, like droughts and desertification.
- The rise in temperature and decrease in rainfall causes droughts.
- Soil erosion reduces soil fertility, which gradually leads to the conversion of fertile land into deserts. This is called desertification.
- We learn about the protection of flora and fauna in protected areas.
- These areas can be divided into wildlife sanctuaries, national parks and biosphere reserves.
- We also read about endemic species of flora and fauna.
- Species which are found only in particular areas are called endemic species.
- We also read about ‘Project Tiger’, the reasons behind the project and its importance.
- The chapter further tells us about the Red Data Book, which tells us about all the endangered species of plants and animals.
- We also learn about migratory birds and where they can be found in India and during which seasons.
- Recycling of paper and its importance has also been emphasised.
- The chapter concludes by telling us about reforestation as a means of tackling the harmful effects of deforestation.
