What is the relationship between a predator and a prey? A predator is an organism that eats another organism. A prey is an organism which the predator eats.
Predator and prey evolve together.
The prey is part of the predator's environment, and the predator dies if it does not get food. The decrease in the number of predator allows an increase in the number of prey. Likewise, the predator is part of the prey's environment, and the prey dies if it is eaten by the predator. The decrease in the number of prey causes the number of predators to decrease as less food is available.
So, the increase and decrease in the population of the predator follows the corresponding increase and decrease in the population of its prey
Two predators with the same prey?
If there are two predators after the same prey, the population of the prey would decrease. Thus, there is less food for both the predators causing a decrease in population size of both predators. Which would then cause a big increase in the number of prey since the population of both its predator decreased.
