Conservation

Correct answer: C. Because it can harm animals and soil

Plastic waste is harmful to wildlife and soil. Exam tip: connect waste control with conservation.

Correct answer: D. Tree plantation

Sowing seeds and caring for saplings is linked with tree plantation. Exam tip: treat plant care as a continuous conservation process.

Correct answer: A. Helping injured or distressed animals

Rescue centres can help injured wild animals. Exam tip: link help and rehabilitation with conservation.

Correct answer: B. They bind soil and reduce erosion

The direct answer is B: tree roots bind the soil and reduce erosion. Roots spread through the ground like a natural net. When rain falls, this net holds soil particles, so water cannot easily carry them away. Roots also slow the movement of water through the soil and help the soil absorb more water. Therefore, vegetation is an important means of soil conservation. Option A is wrong because roots generally strengthen and hold soil rather than weaken it. Option B is correct because binding soil directly reduces removal of the fertile top layer. Option C is wrong because roots do not always drive wildlife away; plants may provide food and shelter for animals. Option D is wrong because trees cannot completely stop rainfall; they may intercept some rain and influence water movement, but rain still occurs. Remember: roots act like an underground net against erosion.

Correct answer: C. It shows the status of species

Counting shows whether a species is increasing or decreasing. Exam tip: connect data with planning.

Correct answer: D. Ecological balance and safety of the future

Conservation keeps nature balanced and future resources safe. Exam tip: link conservation with both present and future.

Correct answer: A. Because wildlife is less disturbed

Low noise helps wildlife remain safe in their natural behaviour. Exam tip: connect quiet behaviour with responsible conservation.

Correct answer: A. Wise use and protection of natural resources

Conservation means protecting natural resources such as forests, water, soil and wildlife, and using them wisely so that they remain available in the future. Deforestation is the opposite of conservation because it destroys habitats and biodiversity. Exam tip: remember conservation as ‘protection plus sustainable use’.

Correct answer: C. Saving organisms and their habitats

Wildlife conservation protects both organisms and habitats. Exam tip: write both terms together.

Correct answer: A. Giving safe environment to wildlife

Sanctuaries are created for wildlife safety. Exam tip: treat sanctuaries as conservation areas.

Correct answer: C. Forest conservation

Stopping deforestation saves habitat and biodiversity. Exam tip: connect deforestation with habitat loss.

Correct answer: D. To protect wildlife populations

Poaching kills animals and can rapidly reduce their populations. Therefore, stopping it is necessary to protect wildlife populations and biodiversity. Reducing forests also harms wildlife, but it is not a purpose of stopping poaching. Exam tip: A ban on hunting is a key wildlife-conservation measure.

Correct answer: B. Protection of trees

The Chipko Movement is remembered as a people’s movement to protect forests and trees from being cut. In this movement, local people showed their opposition to tree felling by embracing or holding the trees. It demonstrated that ordinary communities can participate in conservation and can speak for the protection of their local environment. Therefore, option B is correct. Wildlife trade, stopping rivers, and increasing mining do not describe the central purpose of the movement.

The useful clue is the connection between “Chipko” and hugging trees. The movement made forest protection a public issue and highlighted the value of forests for soil, water, fuel, fodder, wildlife, and local livelihoods. It was not simply a protest by officials; community participation was important. Thus, when the choices are compared, protecting trees is the only option that matches the movement’s known conservation role.

Correct answer: C. Local community

In social forestry, people participate in planting trees and saving resources. Exam tip: remember community-based conservation.

Correct answer: D. Preventing poaching and illegal wildlife trade

The main purpose of wildlife laws is to protect wild animals and plants from poaching, capture, sale and smuggling. Therefore, option D is correct. Preventing deforestation is also important for conservation, but wildlife laws directly target crimes such as poaching and illegal wildlife trade. Exam tip: Remember that poaching and illegal trade are key wildlife offences addressed by such laws.

Correct answer: A. To give organisms food, water and shelter

A habitat is the natural place where an organism lives and obtains the conditions needed for survival. These conditions commonly include food, water, shelter, suitable space, and safety. If a habitat is damaged, an organism may lose its resources even if the species itself is not directly hunted. Habitat protection therefore supports survival, growth, and reproduction.

Option A is correct because food, water, and shelter are basic habitat requirements. Keeping organisms away from their habitat would make survival harder, while increasing hunting or pollution would threaten them. Effective conservation protects the place and the resources that organisms need, rather than focusing only on individual animals.

Correct answer: B. For water birds and aquatic organisms

Wetlands are habitats of many water birds and aquatic organisms. Exam tip: treat wetlands as important habitats.

Correct answer: C. Habitats and nests can be destroyed

Forest fire can damage food, shelter and breeding sites. Exam tip: connect fire with habitat loss.

Correct answer: A. To enable safe animal movement and connect separate habitats

Wildlife corridors form connecting routes between two or more separated wildlife habitats. They allow animals to move relatively safely in search of food, water, mates, and new habitat. Increasing hunting is not their purpose; corridors help reduce the effects of habitat fragmentation. Exam tip: link the word “corridor” with a safe connecting route between habitats.

Correct answer: B. Harmful

Plastic waste can harm organisms and habitats. Exam tip: treat not littering as a citizen responsibility.

Correct answer: D. They are adapted to local environment

Native plants can provide food and shelter to local organisms. Exam tip: connect native plants with habitat improvement.

Correct answer: A. They can affect local species

Invasive species can change local vegetation and habitat. Exam tip: treat them as habitat threats.

Correct answer: B. Using resources while saving them

Sustainable use means using a natural resource carefully so that it remains available in the future. It does not mean stopping every use, nor does it mean taking as much as possible now. The rate of use should remain within the resource’s ability to recover, while waste and unnecessary damage are reduced. This idea can apply to forests, water, soil, fisheries, energy and other resources.

Option B is correct because it expresses the balance between present use and future availability. Finishing resources, illegal trade and burning forests destroy resources instead of conserving them. A sustainable decision asks whether people can meet their current needs without removing the ability of future generations to meet theirs. Thus, the essential words are careful use, conservation, renewal and responsibility toward the future.

Correct answer: C. Protection of habitats and corridors

If habitats and corridors are safe, animals may move less toward settlements. Exam tip: connect conflict with habitat loss.

Correct answer: D. To understand status and changes

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