An example of top-down population regulation in predator-prey species is predation.

Question

Quizplus · Accepted Answer

Predation is an example of top-down population regulation because the predator population controls the prey population by consuming them. If there are too many predators, they may exhaust their food supply and their population will decrease, which in turn will allow the prey population to increase. This cycle can continue to regulate the populations of both predators and prey.
