Which of the following is the most important cause of animals and plants being driven to extinction?

A

Co-extinctions

B

Over-exploitation

C

Alien species invasion

D

Habitat loss and fragmentation

Answer

  • When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. 

  • The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. 

  • Factors such as large body size, habitat loss, and fragmentation (a most important factor), small population and position at a higher trophic level favor extinction.

So, the correct answer is 'Habitat loss and fragmentation'.
