Wildlife

Correct answer: B. One horned rhinoceros

Kaziranga in Assam is famous for the one horned rhinoceros. Exam tip: remember Kaziranga with rhino.

Correct answer: D. Elephant conservation

The direct answer is D: elephant conservation. Project Elephant is an Indian wildlife-conservation programme launched to protect elephants, their habitats and the movement routes connecting those habitats. The reasoning is straightforward: the project name identifies the animal, and its work includes reducing threats such as habitat loss, fragmentation and conflict while supporting elephant protection. Option D is correct. Option A is wrong because tiger protection is associated with Project Tiger, not Project Elephant. Option B is wrong because rhino conservation is a different conservation concern and is not what this project’s name indicates. Option C is wrong because peacock protection is unrelated to Project Elephant. The project protects more than individual elephants: it also helps conserve forests and corridors needed by elephant populations. Exam cue: Project Tiger = tiger; Project Elephant = elephant. Do not choose an option merely because it is another protected Indian animal.

Correct answer: C. To estimate the population and status of wildlife

A wildlife census estimates the number, distribution, and conservation status of wildlife in an area. This information helps identify threatened species and plan conservation measures. Its purpose is not to increase hunting; it is used for monitoring and protection. Exam tip: link a census with population estimation and conservation planning.

Correct answer: C. For picking food and drinking water

An elephant uses its trunk as a versatile tool. It can grasp leaves, grass, fruit, and other food with the tip of the trunk. The trunk also draws up water and guides it into the mouth. In addition to these functions, it can help with smelling, touching, breathing, and making sounds, but the question asks specifically about the listed main use.

Option C says picking food and drinking water, which accurately describes two important functions of the trunk. Flying is not possible for an elephant, weaving webs is associated with spiders, and making snow is not a biological function of any elephant organ. Therefore, option C is the correct choice. The answer follows by linking the trunk with feeding and drinking.

Correct answer: D. Himalayan mountain region

Direct answer: Option D, Himalayan mountain region. Musk deer is a small mountain-dwelling deer associated with high Himalayan forests, alpine meadows, and cold mountainous habitats. Its body and behaviour suit steep, cold terrain rather than hot or coastal environments. Option D is correct because the Himalaya provides the characteristic high-altitude habitat of this animal. Option A, sea coast, is a low-lying marine environment and is not the usual habitat of musk deer. Option B, hot desert, lacks the cool mountain vegetation and conditions it needs. Option C, saline marsh, is a salty wetland and is not the normal habitat of this forest and mountain species. The word “musk” refers to a substance produced by the male, not to a coastal or desert adaptation. Exam cue: musk deer is a Himalayan wildlife example.

Correct answer: A. Indian wild ass

The Indian wild ass is a famous animal linked with the Rann of Kachchh. Exam tip: remember Kachchh with wild ass.

Correct answer: B. Cold high Himalayan climate

Yak is found in cold high Himalayan regions. Exam tip: connect yak with cold mountain habitats.

Correct answer: C. Tiger

The direct answer is C: tiger. The Sundarbans is a large mangrove region in the delta of the Ganga, Brahmaputra and Meghna rivers, and it is especially famous for the Royal Bengal tiger. Reason step by step: identify Sundarbans as a tidal mangrove forest; connect that habitat with its well-known wildlife; select tiger. Option C is correct because the Royal Bengal tiger is a major symbol and protected species of the Sundarbans. Option A, camel, is wrong because camels are adapted mainly to dry desert regions. Option B, yak, is wrong because yaks are associated with cold high mountain areas. Option D, musk deer, is wrong because musk deer are linked mainly with Himalayan forest habitats, not mangrove deltas. Memory cue: Sundarbans means mangroves and Royal Bengal tiger.

Correct answer: A. They provide food to grazing herbivores

Grasslands provide food to deer nilgai and other grazing animals. Exam tip: connect grasslands with herbivores.

Correct answer: B. Because they are linked with breeding and safety of young ones

The direct answer is B: nests are linked with breeding and the safety of young birds. A nest is a place where a bird may lay eggs, incubate them and care for hatchlings. It can provide shelter and reduce danger from weather and predators. Leaving a nest safe helps the parents continue caring for eggs and chicks without disturbance. Option B is correct because it states this biological purpose. Option A is wrong because nests do not increase mining. Option C is wrong because a nest does not stop a river. Option D is wrong because birds' nests do not cut forests; in fact, birds depend on suitable vegetation and trees. People should avoid touching, removing or disturbing nests, while also following safe wildlife guidance. Memory cue: nest means eggs, chicks and protection.

Correct answer: D. It can disturb wildlife

Loud noise can affect animal behaviour and safety. Exam tip: treat quiet behaviour as responsible tourism.

Correct answer: A. Elephant

Elephant is a large herbivorous wild animal dependent on plants. Exam tip: remember elephant as a herbivore and a large animal.

Correct answer: B. Rivers lakes and marshy areas

The direct answer is B: rivers, lakes and marshy areas. A habitat is the place that provides an organism with the conditions it needs. Crocodiles are reptiles commonly associated with freshwater or wet habitats, where they can find water, shelter, food and suitable places for resting or breeding. Step by step: a crocodile needs access to water; rivers, lakes and marshes provide that water; these habitats also support fish and other animals that may become food; banks, vegetation and mud can provide shelter and resting places. Option A is wrong because a dry desert normally lacks the permanent water needed by crocodiles. Option B is correct because it lists suitable aquatic and wetland habitats. Option C is wrong because snowy peaks are cold, high and generally unsuitable for crocodile life. Option D is wrong because an open market is a human-built place, not a natural wildlife habitat. Particular crocodile species can differ in range, but the broad habitat association in the question is accurate. Memory cue: crocodile means water, wetland and riverbank.

Correct answer: D. When a species is at risk of extinction

Special conservation programmes are run to protect threatened species. Exam tip: connect declining numbers with special conservation.

Correct answer: A. Spreading awareness and the message of saving habitats

Students can help conservation through awareness and responsible behaviour. Exam tip: consider public participation important.

Correct answer: B. Because waste can harm animals and habitat

Waste can damage wildlife health and natural habitat. Exam tip: connect cleanliness with conservation.

Correct answer: C. They help the new generation grow safely

Safe breeding places help maintain wildlife populations. Exam tip: connect breeding with conservation.

Correct answer: D. Disturbing animals

Disturbing animals can affect their behaviour and safety. Exam tip: consider not disturbing wildlife as correct behaviour.

Correct answer: C. They keep herbivore numbers balanced

Carnivores control herbivore numbers through predation. Exam tip: connect carnivores with balance.

Correct answer: A. By protecting habitats and reporting illegal hunting

Local people play a big role through awareness and correct reporting. Exam tip: consider local participation important.

Correct answer: B. It shows feeding relations and energy flow among organisms

A food chain shows who depends on whom for food. Exam tip: connect feeding relations with ecological balance.

Correct answer: A. They provide water food and shelter

Riverbanks provide water and food to many animals. Exam tip: understand riverbanks as important habitats.

Correct answer: B. Tiger

Tiger gets food by hunting so it is a carnivorous predator. Exam tip: connect tiger with the food chain.

Correct answer: A. Monkey

The direct answer is A: monkey. To solve this, connect the animal’s usual food and living place with the option. Monkeys commonly live in or around trees and eat fruits, leaves, seeds, flowers and sometimes insects. The reasoning is: trees provide the monkey with food and climbing or resting places; fruits are therefore an important link between trees and monkeys. B, crocodile, is mainly associated with rivers, lakes and wetlands and is not the best example of an animal dependent on trees and fruits. C, camel, is adapted to dry regions and feeds mainly on desert plants, shrubs and grasses; it is not a tree-and-fruit example. D, vulture, is a scavenging bird that feeds mainly on dead animals and commonly uses open areas or cliffs, not fruits as its main food. Thus A fits both clues. Exam cue: tree plus fruit usually points to a monkey in a basic wildlife question.

Correct answer: B. In breeding and keeping young ones safe

Nests are necessary for bird breeding and safety of young ones. Exam tip: connect nests with bird conservation.
