7. What is the relationship between Predator and Prey?

A predator is an animal that eats another animal. The animal getting eaten is the prey.

The graph above shows that as the population of the predator (fox) gets too high then the prey population (rabbit) goes down. When the prey population goes down then the predator doesn't have enough food and the prey population goes down. Because there are less predators then the prey population goes back up. This goes on and on and on....
