A Correct answer
Explanation

A naturally occurring sanctuary, such as an island, which protects species from getting hunted, predated or poached is called as a wildlife refuge. It is also known as a wildlife sanctuary.

Why should we conserve biodiversity?

  1. We should preserve the biodiversity we have inherited

  2. A loss of diversity may lead to a loss of ecological stability

  3. Both (a) and (b)

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A loss of biodiversity will result in loss of ecological balance. Biodiversity is an integral part of our environment.

Multiple choice

What is a common goal of a marine protected area (MPA)?

  1. To prohibit tourism in that area forever.

  2. To allow only government vessels to pass through it.

  3. Increase fish populations that can be caught in surrounding waters.

  4. To introduce new species into a marine ecosystem.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Marine protected areas are designed to conserve biodiversity and often lead to a spillover effect, where fish populations increase and migrate to surrounding areas, benefiting local fisheries.

Multiple choice

Why is biodiversity important to a marine ecosystem?

  1. Larger species can help protect smaller species from predators.

  2. Fish have a greater variety of food so they will want to stay.

  3. Diversity means a better chance of surviving outside threats.

  4. Greater diversity means an ecosystem will grow larger.

Multiple choice natural vegetation and wildlife of india and world resources of india and world general knowledge

Consider the following statements.
1) National Parks are a special category of protected areas of land and sea coasts where people are an integral part of the system.
2) Sanctuaries are concerned with conservation of particular species.
3) Biosphere Reserves are connected with the habitat of a particular wild animal.
Which of the statements given above is/are correct?

  1. 1 , 2 and 3

  2. Only 2

  3. 1 and 2

  4. 1 and 3
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Statement 1 is incorrect because Biosphere Reserves, not National Parks, integrate human communities as part of the conservation system. Statement 3 is incorrect because Biosphere Reserves focus on entire ecosystems and genetic diversity rather than a single animal species. Wildlife sanctuaries (Statement 2) are indeed often designated to protect specific species or groups of species.

Explanation

Biosphere reserves serve three main functions: conservation of biodiversity and ecosystems (in-situ), sustainable economic and human development, and logistic support for research, monitoring, and education. All three statements accurately reflect these core pillars.

Multiple choice

How does recycling conserve natural resources?

  1. It prevents garbage from being burned

  2. It saves on the amount of plastic used to manufacture bags

  3. It saves on the amount of fuel used by garbage trucks

  4. It allows us to re-use products and manufacture new ones
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Recycling conserves natural resources by allowing us to process used materials into new products, reducing the need to extract raw materials from the Earth. For example, recycling aluminum cans reduces the need to mine bauxite ore, saving both resources and energy.
