Answer 1

Answer. (c) destruction of habitat

Explanation.

Wildlife includes all those naturally occurring plant and animal species which are neither cultivated, or domesticated nor tamed. Several hundred organisms are endangered or on the verge of extinction. The reasons are deforestation, pollution, killing, over exploitation etc. The most important among them is deforestation or destruction of their natural habitat because it will affect the species (flora and fauna) of complete area and not only the few organisms.

The natural habitat may be destroyed by man for his settlements, grazing grounds, agriculture, mining, industries, dam building etc. As a consequence of this, the species must adapt to the changes, move elsewhere or may succumb to predation, starvation or disease, or eventually dies.
