 If the number of predators was to increase, the entire food chain would be affected as any prey falling below that specified predator in the food chain will become prey.If the prey is not given enough time by the predator to repopulate, this could not only cause endangerment and extinction in the prey, but the predator as well.Contradicting a decrease in population size, if a particular species reproduces too rapidly, this will cause an increase in population size, thus affecting the environment around them.
