Ecological theories of persistent predator–prey cycles are supported by the apparent existence of such cycles in nature, for instance between the lynx and hare in Canada 3.
Predator-prey cycles are based on a feeding relationship between two species: if the prey species rapidly multiplies, the number of predators increases - until the predators eventually eat so many ...

Predator-prey cycles show the natural rise and fall of numbers of predators and prey over time. ... A predator-prey graph shows the numbers of predators and prey in an ecosystem over time.
Populations of predators and their prey usually follow predictable cycles. When the number of prey increases -- perhaps as their food supply becomes more abundant -- predator populations also grow.
Predator-prey cycles show the natural rise and fall of numbers of predators and prey over time. All organisms in a food web depend upon each other and changes to one can affect the others.
