Animals get extinct mainly due to

biology main natural resources classification of threatened species red data book conservation of wildlife

  1. Predation

  2. Habitat destruction

  3. Afforestation

  4. Pollution

Show answer
Correct Option: B
Explanation:

Habitat destruction is the process in which natural habitat is rendered functionally unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity. Habitat destruction by human activity is mainly for the purpose of harvesting natural resources for industry production and urbanization. Clearing habitats for agriculture is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, trawling and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide.

Therefore, the correct answer is option B.

biology main natural resources classification of threatened species red data book conservation of wildlife

  1. Endemic

  2. Extinct

  3. Endangered species

  4. Evolution

Show answer
Correct Option: C
Explanation:
  1. A species whose habitat is restricted to a particular area is known as endemic species. 
  2. A species that has died out and hence is out of site is called extinct species.
  3. A species which is less in number and can be extinct in near future is called endangered species.
  4. The origination and development of new life forms on earth is called evolution.
Thus the correct answer is option 'Endangered species'.
