How can predators affect the population growth?
They grow more slowly, reproduce less, and populations decline. As predator populations increase, they put greater strain on the prey populations and act as a top-down control, pushing them toward a state of decline. Thus both availability of resources and predation pressure affect the size of prey populations.
