Conservation

Correct answer: B. Prey species and their habitats also need protection

Protection of a predator also depends on prey species and habitat. Exam tip: view the food chain as a whole before choosing the answer.

Correct answer: C. When only fast growing alien species are planted and local biodiversity is ignored

Wrong species selection can affect native vegetation and biodiversity. Exam tip: focus on the quality of plantation.

Correct answer: A. Habitat fragmentation and obstruction to wildlife movement

Roads can separate habitats and corridors maintain connectivity. Exam tip: connect corridors with safe movement.

Correct answer: B. Because habitat quality and genetic diversity are also important

Conservation also considers habitat and diversity along with numbers. Exam tip: do not depend on only one indicator.

Correct answer: A. Pressure on surrounding zone and reduced animal movement

Land use around protected areas also affects wildlife. Exam tip: consider impacts beyond the boundary too.

Correct answer: B. Balance between strict conservation and regulated use

The core zone is more protected and the buffer zone may allow regulated use. Exam tip: link zonation with balanced conservation.

Correct answer: B. When no safe habitat is available for release

After captive breeding animals need safe natural habitats. Exam tip: connect ex situ conservation with habitat protection.

Correct answer: A. Because it increases cooperation in rule following and monitoring

Community participation makes conservation practical and sustainable. Exam tip: connect consent with successful implementation.

Correct answer: B. Controlling it to protect native grassland and species

Invasive species can reduce native biodiversity. Exam tip: identify alien species as a possible threat.

Correct answer: A. To reduce risk of collision and stress for animals

Slow speed helps wildlife safety and a calm environment. Exam tip: connect tourism rules with conservation.

Correct answer: B. Because awareness livelihood options and monitoring are also necessary

Not only penalties but behaviour and alternatives also matter. Exam tip: choose a multi level conservation approach.

Correct answer: B. Habitat resources should also be checked along with count

Water and habitat are important along with wildlife number. Exam tip: link data with resource condition.

Correct answer: B. Forests are linked with soil runoff and water sources

Forests play an important role in water and soil balance. Exam tip: connect forests with the water cycle.

Correct answer: A. When local people depend on forest resources and alternatives are not provided

Restrictions without livelihood alternatives can increase dissatisfaction. Exam tip: understand conservation through the social aspect too.

Correct answer: A. Because they can be ecological indicators and part of food chains

Small organisms also play important roles in ecosystems. Exam tip: connect biodiversity with all organisms.

Correct answer: A. Less disturbance in natural behaviour of wildlife

Quiet zones help protect wildlife from stress. Exam tip: connect noise control with behaviour protection.

Correct answer: B. Deciding after understanding local ecology weather and safety rules

Fire management needs great care and expertise. Exam tip: connect fire with both risk and management.

Correct answer: B. Because rehabilitation and habitat safety are also needed after rescue

Rescue centres help but permanent conservation is linked with habitat. Exam tip: understand rescue and rehabilitation together.

Correct answer: A. It can help a species adapt to changes

Genetic diversity can increase the long term strength of a species. Exam tip: connect diversity with adaptation.

Correct answer: A. Because both can improve planning by giving different kinds of information

Scientific and local knowledge together can support stronger decisions. Exam tip: treat knowledge sources as complementary.

Correct answer: A. Habitat of grassland dependent species may decrease

Direct answer: Option A is correct. Grassland is not automatically wasteland; it is a natural habitat with its own plants, insects, birds and grazing animals. Step by step: grassland species need open, grassy conditions; planting trees changes light, soil moisture and vegetation structure; open-habitat species may lose food, shelter and breeding space; their populations can decline. Option A correctly identifies habitat loss. Option B is wrong because grasslands can support considerable biodiversity and do not always destroy it. Option C is wrong because different species need different habitats; forests are not suitable for every organism. Option D is wrong because protecting grassland is an important part of conservation. Tree planting is useful only when the location and ecosystem are suitable. Memory cue: conservation protects suitable habitats, not merely more trees.

Correct answer: A. Because presence of many species can be known near water sources

Water sources are important places to understand wildlife activity. Exam tip: connect monitoring with planning.

Correct answer: B. Community cooperation with alternative fuel and regulated use

Heavy dependence on fuelwood can put strong pressure on forests because repeated cutting removes trees faster than they can recover. A lasting solution should reduce this pressure while recognising the daily needs of local people. Cleaner or alternative fuels, efficient devices, regulated collection, tree planting, and community participation can work together. Therefore, option B is correct. Strict punishment alone may not solve the underlying need, and declaring all local people illegal is unfair and ineffective.

The question asks for a practical conservation measure, so the best answer must be both environmentally useful and socially workable. If people receive accessible alternatives and help in managing resources, they have a stronger reason to protect the forest. Controlled use can prevent unnecessary cutting while allowing essential needs to be met. Removing wildlife or increasing wood collection would damage the ecosystem. Thus alternative fuel combined with regulated use and community cooperation is the sound choice.

Correct answer: A. Because reducing demand awareness and local monitoring are also necessary

The direct answer is A: reducing demand, awareness and local monitoring are also necessary. Illegal wildlife trade is a chain involving poachers, transporters, sellers and buyers. Border checks can intercept some shipments, but trade may move through other routes if demand and local collection continue. Reducing demand makes the illegal business less profitable. Public awareness can discourage buying illegal wildlife products, while local communities and authorities can report poaching and protect habitats. Option A is correct because it describes a combined strategy. Option B is wrong because border checking does not always increase trade; effective checking can stop or deter it. Option C is wrong because illegal trade harms populations and can push species toward decline or extinction. Option D is wrong because awareness can influence consumer choices and support reporting, even though it is not sufficient alone. The best conservation response uses enforcement, cooperation, education and habitat protection together. Memory cue: stop the trade at the border, source, seller and buyer.

Correct answer: A. Forests can help hold soil and reduce runoff and landslide risk

The direct answer is Option A: forests can hold soil and reduce runoff and landslide risk. Tree roots bind soil particles, while trunks, branches, leaves and forest litter slow the movement of rainwater. More water can then enter the soil gradually instead of rushing downhill. This reduces soil erosion and, on suitable slopes, can lower the chance of landslides and sudden runoff. Forests cannot stop every disaster, so this is a helpful connection, not an absolute guarantee. Option A is correct because it describes an important protective function of vegetation. Option B is wrong because forests do not always increase disasters; healthy forests often reduce some risks, although poorly managed land can still face hazards. Option C is wrong because roots and soil are closely connected. Option D is wrong because forests have ecological, climatic, water, soil and livelihood value, not merely timber value. Exam cue: connect forest conservation with soil, water and safety.
