Wildlife

Correct answer: A. Habitats may break and accidents may increase

Unplanned roads can cause habitat fragmentation and wildlife accidents. Exam tip: connect road impact with habitat connectivity.

Correct answer: A. To understand population and conservation status

Monitoring shows whether species status is improving or declining. Exam tip: connect monitoring with conservation management.

Correct answer: A. Habitat-based conservation

To save a species, its habitat must be protected. Exam tip: remember the relation between rhinoceros and marshy grassland.

Correct answer: A. Scavenger

Organisms that feed on the remains of dead animals and help keep the environment clean are called scavengers. Vultures and hyenas are examples. Decomposers, such as bacteria and fungi, break dead matter into simpler substances, so they are different from scavengers. Exam tip: an animal that eats dead animals is a scavenger.

Correct answer: A. Availability of prey species and habitat will improve

Tigers need prey, water and safe habitat. Exam tip: connect top predators with the whole ecosystem.

Correct answer: A. Spreading awareness and adopting responsible behaviour toward nature

Students can contribute to conservation through awareness and responsible behaviour. Exam tip: write public participation as a conservation measure.

Correct answer: A. Better and safer habitat

Wildlife needs food, water and safe habitat with low disturbance. Exam tip: remember the components of safe habitat.

Correct answer: A. To save wildlife, habitat, food chain, laws and public awareness must be protected together

Successful conservation depends on many connected measures. Exam tip: keep the conclusion broad and balanced.

Correct answer: A. Good natural habitat

A good habitat fulfils the basic needs of organisms. Exam tip: connect habitat with food, water and shelter.

Correct answer: B. Habitat and food will decrease

The direct answer is B: habitat and food will decrease. A forest is not only a collection of trees; it is a habitat providing shelter, nesting places, water, food and breeding space. Step by step: trees are cut; the living space becomes smaller or fragmented; plants, fruits, insects and other food sources decrease; animals may be forced to move, compete or die. Option B is correct because habitat loss and reduced food are immediate major threats. Option A is wrong because cutting trees does not immediately increase wildlife; it usually reduces carrying capacity. Option C is wrong because wild animals do not automatically become domestic. Option D is wrong because deforestation can increase environmental damage and cannot make pollution disappear by itself. Memory cue: cutting forests means losing homes and food.

Correct answer: C. Gir forest

Asiatic lions are mainly linked with Gir forest in Gujarat. Exam tip: remember the correct match of Gir and lion.

Correct answer: D. One-horned rhinoceros

The direct answer is D: one-horned rhinoceros. Kaziranga National Park is in Assam and is internationally famous for its large population of the Indian one-horned rhinoceros. Reason step by step: locate Kaziranga in Assam; recall its major protected animal; match that animal with the options. Option D is correct. Option A, camel, is wrong because camels are chiefly associated with arid and desert environments. Option B, snow leopard, is wrong because snow leopards live in high, cold mountain regions, not the lowland grasslands and wetlands for which Kaziranga is known. Option C, peacock, is wrong because although peacocks may occur in India, they are not Kaziranga’s special identifying wildlife. Memory cue: Assam—Kaziranga—one-horned rhino.

Correct answer: A. Giving legal protection to organisms and their habitats

The direct answer is A: national parks give legal protection to organisms and their habitats. A national park is a protected area created to conserve plants, animals, ecosystems and important natural processes. Rules restrict activities such as hunting, habitat destruction and uncontrolled resource use. Therefore protection covers both the wildlife and the place where it lives; protecting only an animal without its habitat would not be enough. Option A is correct. Option B is wrong because illegal hunting is prohibited, not increased. Option C is wrong because pollution of rivers harms ecosystems and is contrary to conservation. Option D is wrong because turning forests into mines destroys habitats and is not the purpose of a national park. Exact rules can differ by law and protected-area category, but the central contribution is conservation through legal protection and management. Memory cue: national park means nature has priority over destructive human activities.

Correct answer: B. One that is at risk of extinction

An endangered species has a risk to its survival. Exam tip: connect it with need for special protection.

Correct answer: C. They become the first source of energy

Plants are producers in the food chain and pass energy forward. Exam tip: understand food chains as starting from plants.

Correct answer: A. Their food and hiding place may decrease

Grasslands provide food and shelter for herbivores. Exam tip: connect grassland with herbivore habitat.

Correct answer: D. Camel

Camel is adapted to dry desert conditions. Exam tip: remember the match between Thar and camel.

Correct answer: A. Rivers and water bodies

A crocodile is strongly associated with aquatic habitats. It commonly lives in or near rivers, lakes, wetlands, marshes, and other water bodies, where it can swim, rest on banks, and find food. Its body and behaviour are suited to water and nearby land, although the exact habitat differs among crocodile species. At school level, the river and water-body association is the key fact.

Option A is correct because rivers and water bodies provide the characteristic habitat of crocodiles. A dry desert does not normally provide the permanent water and conditions they need. A high snowy peak is too cold and lacks the suitable aquatic environment, while a city road is not a natural habitat. The question tests habitat recognition, so connect crocodile with freshwater or other suitable aquatic environments rather than with dry, snowy, or urban places.

Correct answer: B. Wildlife is an important part of biodiversity

Biodiversity includes the variety of different organisms. Exam tip: treat wildlife as part of biodiversity.

Correct answer: C. They pass energy to the next level

Herbivores pass plant energy forward in the food chain. Exam tip: remember the order of energy flow.

Correct answer: A. They may face food shortage

Carnivores like tigers depend on prey species. Exam tip: write the predator-prey relationship.

Correct answer: B. When habitat shrinks and animals come near settlements

When habitat shrinks, animals may enter human areas in search of food and space. Exam tip: write habitat loss as a cause of conflict.

Correct answer: C. They provide food, water and resting places

Wetlands are important habitats for water and migratory birds. Exam tip: connect wetlands with bird conservation.

Correct answer: D. Connecting separate habitats and allowing safe movement

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

Correct answer: A. Movement and breeding can become difficult

Habitat fragmentation can obstruct safe movement of organisms. Exam tip: write fragmentation as a conservation problem.
