Conservation

Correct answer: A. Protecting species and their habitats

Conservation aims to protect both organisms and their natural habitats. Exam tip: write habitat protection as a main point.

Correct answer: B. Because it protects food, shelter and biodiversity

Direct answer: Option B is correct. Forests are ecosystems that provide food, shelter, nesting places, breeding areas, shade, and protection for many plants and animals. They also support soil, water cycles, and biodiversity, meaning the variety of living organisms. When deforestation is stopped, these habitats are less likely to be destroyed, so many species have a better chance to survive. Option A is wrong because stopping deforestation does not mean that all industries must close; sustainable use and careful planning are possible. Option B correctly connects forest protection with food, shelter, and biodiversity. Option C is wrong because forest protection does not make all wild animals domestic; wild animals remain wild. Option D is wrong because deforestation generally contributes to habitat loss and may encourage environmental degradation, while stopping it does not increase deserts. Memory cue: protect forests, protect habitats, protect biodiversity.

Correct answer: C. Legally protected natural areas

In national parks, wildlife and habitats get legal protection. Exam tip: treat them as protected areas.

Correct answer: B. Because poaching can reduce species numbers

The direct answer is B, because poaching can reduce species numbers. Poaching means illegally hunting, capturing, or killing wild animals, often for meat, skin, horns, tusks, feathers, or illegal trade. Step by step: poaching removes animals directly from their natural populations; repeated removal reduces the number of breeding adults; fewer adults can produce fewer young; very severe or continued poaching can make a species threatened or locally extinct. Therefore stopping poaching is necessary for conservation. Option A is wrong because poaching itself does not mean cutting forests; deforestation is a different threat, though both are harmful. Option B is correct and gives the direct effect. Option C is wrong because killing animals can disturb food chains rather than strengthen them. Option D is wrong because poaching does not necessarily reduce pollution. Exam cue: poaching is a direct human pressure on animal populations.

Correct answer: C. It can increase habitat and green cover

Tree plantation can improve green cover and habitat for some organisms. Exam tip: write it as a conservation measure.

Correct answer: D. Planting trees and saving resources with community participation

Social forestry depends on participation of local people. Exam tip: remember community-based conservation.

Correct answer: A. Public participation to save trees from cutting

The Chipko Movement is an example of tree protection and public participation. Exam tip: connect it with forest conservation.

Correct answer: C. They can help in monitoring, awareness and rule-following

Local people can strengthen conservation at ground level. Exam tip: write public participation as a conservation measure.

Correct answer: A. To control illegal hunting and trade

Wildlife laws provide formal rules for protecting animals, plants, and their habitats. They can restrict illegal hunting, capture, trade, and other activities that threaten species. Enforcement, protected areas, and penalties help discourage wildlife crime and give endangered populations a better chance to survive. Laws work best when people and authorities follow and enforce them.

Option A is correct because controlling illegal hunting and trade is a major purpose of wildlife legislation. Removing forests, increasing pollution, or making every organism domestic would damage natural ecosystems. A law is not merely a suggestion; it creates a legal framework for conservation and holds people accountable when they harm wildlife.

Correct answer: B. Because it protects the whole ecosystem, including food, water, shelter and breeding sites

Habitat conservation protects the ecological conditions of an area, including food, water, shelter and breeding sites. Therefore, it benefits many plant and animal species living there at the same time, making it broader than conservation focused on a single species. Option A describes species-focused conservation, not habitat conservation. Exam tip: mention that habitat conservation protects an entire ecosystem and multiple species.

Correct answer: C. Because they are habitats of water birds and aquatic organisms

Wetlands support many water birds and aquatic organisms. Exam tip: treat wetlands as habitats worth conserving.

Correct answer: D. Because fire can destroy food, shelter and breeding sites

Forest fires can damage vegetation and wildlife habitats. Exam tip: connect fire with habitat loss.

Correct answer: B. They connect separate habitats and help safe movement

Corridors maintain habitat connectivity and help animal movement. Exam tip: connect corridors with habitat connectivity.

Correct answer: C. Connecting habitats through corridors

Corridors connect small habitats and help movement and breeding. Exam tip: treat corridors as a solution to fragmentation.

Correct answer: A. Because people understand rules and importance of nature

Aware people can follow conservation rules better. Exam tip: write education and awareness as measures.

Correct answer: B. It can harm wildlife and habitat

Plastic waste can be harmful to organisms and their natural habitats. Exam tip: remember responsible behaviour.

Correct answer: C. Because they fulfil life and habitat needs of wildlife

Water sources are linked with life and food chains of many organisms. Exam tip: write water as an essential habitat component.

Correct answer: A. Because native plants are adapted to local organisms and habitat

Native plants support local ecology better. Exam tip: connect native species with habitat restoration.

Correct answer: A. They can compete with local species and change habitat

Invasive species can affect native vegetation and organisms. Exam tip: treat them as a habitat threat.

Correct answer: A. They help improve green cover and habitat

Planting trees and restoring forests can improve habitat. Exam tip: write both green cover and habitat.

Correct answer: A. Using resources so future needs are also protected

Sustainable use balances present and future needs. Exam tip: remember the simple meaning of sustainable use.

Correct answer: A. Protection of habitats and corridors

When habitats and corridors are protected, animals may enter settlements less. Exam tip: connect conflict with habitat loss.

Correct answer: A. It helps understand conservation status and changes

Monitoring shows the condition of species and habitat. Exam tip: connect data with conservation management.

Correct answer: A. When rules are followed and organisms are not disturbed

Responsible tourism can increase awareness and protect habitat from harm. Exam tip: write responsible tourism.

Correct answer: A. Because pollution can harm water, soil and food chains

Pollution can harm organisms directly and indirectly. Exam tip: write pollution as an environmental threat.
