Role of Predation


 *  Two Reasons: **

1.Top level carnivores help maintain populations of herbivores and omnivores. Without these keystone predators, the numbers of certain grazers would explode, disrupting the natural balance between hunters and the hunted. If the grasslands became too overpopulated with grazers, all of the vegetation would disappear. Overgrazing may lead to desertification because there are no plants to anchor the soil to the ground, causing the topsoil to blow away.

2.Higher level predators help maintain biodiversity by preventing one species from becoming dominant. Lions, cheetahs, leopards, and other carnivores are not selective hunters.
