Predator-prey relationship



An interaction between two organisms of unlike species in which one of them acts as 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 preys 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 preys decline. This results in food scarcity for predators that can eventually lead to the death of many predators.
