Question

Which of the following is the main reason for the extinction of animals?
(A)Predation
(B)Pollution
(C)Destruction of habitat
(D)Felling of trees

Answer 1

Hint: The main reason for the extinction of animals is destruction and disturbance in the type of natural environment in which a particular species of organism lives. These places are where the species can find food, shelter, protection, and mates for reproduction.

Complete answer:
The main reason for the extinction of animals is the destruction of the habitat. Destruction of habitat is that the process during which natural habitat is rendered unable to support the species that lived in it. Increasing urbanization and industrialization has resulted in encroachment of forest areas resulting in the destruction of habitat. As a result, the natural flora and fauna are endangered and a few become extinct.

Additional Information: Extinction is defined as the termination of a sort of organism or of a group of kinds (taxon), usually a species. The extinction is usually considered to be the death of the last animal present of the species, although the capacity to breed and recover may be lost before this time. As you know that the potential range of a species always varies and is very large, determining this moment is difficult and is typically done retrospectively. Mass extinctions are very rare events; however, isolated extinctions are quite common. Only recently extinctions have been recorded and scientists became alarmed at the present high rate of extinctions.
So, the correct answer is ‘Destruction of habitat’.

Note: The main reason for habitat degradation worldwide is agriculture, with an urban area, logging, mining, and a few fishing practices close behind. The degradation of a species' habitat will change the fitness landscape too much that the species is no longer able to survive and becomes extinct.
