What is the role of predator in balancing the ecosystem?

1.	What is the role of predator in balancing the ecosystem?
Answer» 1. Predators keep prey population under control. If predators are lacking from the ecosystem, the prey population will rise without any control. Their high density may cause instability in ecosystem. 2. Predators also help in maintaining the species diversity in a community. This is done by reducing the intensity of competition among competing prey species. 3. Predators control the pest species and thus can be used for natural biological control measures in an ecosystem. E.g. frog controlling the locust population. 4. Predators also control the invading exotic species and stop their rapid spread of such species.
