Predator-prey relationship

An interaction between two organisms of unlike species in which one of them acts as a predator that captures and feeds on the other organism that serves as the prey
In ecology, predation is a mechanism of population control. Thus, when the number of predators is scarce the number of prey should rise. When this happens the predators would be able to reproduce more and possibly change their hunting habits. As the number of predators rises, the number of prey declines. This results in food scarcity for predators that can eventually lead to the death of many predators.
