What is the relationship between a predator and a prey?
A predator is an organism that kills and feed on other organisms. The organisms that are eaten are called the prey.



Two predators with the same prey.
However,this cycle changes when another predator of the same prey is introduced into the same biotic environment.Prey will be hunted and fed on continuously until the number falls until it is almost extinct.Food is now scarce for both predators.Therefore the population of both predators will drop as there is hardly any prey.This fragile cycle might break as time passes and both prey and predator goes extinct unless predators hunt for a different prey and the prey evolves to be able to evade the predator.
