NCERT Exemplar Solution for Class 8 Science Chapter-7- Conservation of Plants and Animals
Nature provides balance to life through forests, wildlife, water, and biodiversity. The chapter “Conservation of Plants and Animals” introduces students to the importance of protecting forests and wildlife from extinction and environmental damage. It explains how human activities such as deforestation, urbanisation, industrial growth, and excessive use of natural resources are affecting ecosystems around the world. This chapter also highlights the role of wildlife sanctuaries, national parks, biosphere reserves, and reforestation in maintaining ecological balance. The NCERT Exemplar Solution for Class 8 helps students understand important scientific concepts through practical and reasoning-based questions. By studying the NCERT Exemplar Solution, learners can improve their understanding of biodiversity conservation and environmental protection. These detailed NCERT solutions for class 8 also support better preparation for school examinations while creating awareness about sustainable living and the need to preserve natural resources for future generations.

Importance of Conservation of Forests and Wildlife
Forests are known as the green lungs of the Earth because they absorb carbon dioxide and release oxygen. They provide shelter to countless plants, animals, birds, insects, and microorganisms. Forests also help in maintaining soil fertility, regulating rainfall, preventing floods, and controlling climate conditions. However, due to large-scale cutting of trees for agriculture, industries, roads, and buildings, forests are disappearing rapidly.
The destruction of forests is called deforestation. Deforestation leads to soil erosion, floods, global warming, droughts, and loss of biodiversity. Animals lose their natural habitats and many species become endangered. Some species may even become extinct permanently. The chapter explains how conservation efforts help protect wildlife and maintain ecological balance. Wildlife sanctuaries are protected areas where animals can live safely without hunting or disturbance. National parks conserve both flora and fauna along with their natural habitats. Biosphere reserves protect large ecosystems and preserve traditional lifestyles of local communities as well.
The NCERT Exemplar Solution for Class 8 includes important questions based on conservation methods, causes of deforestation, and effects of environmental destruction. These solutions encourage students to think scientifically about environmental issues and their impact on life.
Endangered Species and Ecosystem Balance
An ecosystem consists of living organisms and their surroundings interacting with each other. Every organism in an ecosystem has an important role. If one species disappears, the balance of the ecosystem may get disturbed. The chapter introduces students to endangered species, which are animals or plants at risk of extinction. Several animals like tigers, elephants, rhinoceroses, and lions are protected in India through wildlife conservation programs. Projects such as Project Tiger were started to increase the population of endangered animals. Conservation programs also create awareness among people about protecting wildlife from illegal hunting and habitat destruction.
Migration of birds is another important topic discussed in the chapter. Many birds travel long distances during specific seasons in search of suitable climate, food, and breeding conditions. Conserving wetlands and forests helps protect migratory birds and their habitats. The Red Data Book is an important source of information about endangered plants and animals. It keeps records of species that are rare, threatened, or at risk of extinction. Students studying the NCERT Exemplar Solution learn the significance of maintaining biodiversity and conserving species for ecological stability.
The chapter also explains recycling and reforestation. Recycling paper helps save trees, while reforestation involves planting trees to restore damaged forests. These methods are important for reducing environmental damage and promoting sustainable development.
Role of Human Beings in Environmental Protection
Human activities have a direct impact on nature. Pollution, overpopulation, industrialisation, and excessive use of resources are causing environmental imbalance. This chapter teaches students that protecting nature is not only the responsibility of governments and organisations but also of individuals.
Simple habits like planting trees, saving paper, avoiding plastic waste, and protecting wildlife can contribute to environmental conservation. Students are encouraged to participate in awareness campaigns and understand the importance of sustainable living.
The NCERT solutions for class 8 provide detailed explanations that simplify difficult concepts related to biodiversity and conservation. These solutions help students answer conceptual questions confidently and improve their analytical thinking skills. Understanding conservation is important because it connects science with real-life environmental problems. The chapter encourages students to become responsible citizens who value forests, wildlife, and natural resources. Learning these concepts also helps develop awareness about climate change and ecological sustainability.
Benefits of Studying This Chapter
This chapter helps students understand how natural resources support life on Earth. It creates awareness about the importance of biodiversity and environmental conservation. Students also learn scientific terms such as deforestation, afforestation, ecosystem, endangered species, and wildlife sanctuary in a practical and meaningful way.
The NCERT Exemplar Solution for Class 8 strengthens conceptual clarity by providing practice questions that focus on reasoning and application. Regular study of these solutions improves subject understanding and examination performance while developing environmental awareness among learners.
