Biology Graphs: Predator and Prey

By L Chapman

Predators eat prey and maintain the health of the prey populations. The predators eat the old, sick, weak and injured in prey populations. As the population of the prey increases then the predator population will increase. As the predators increase the number of prey decrease.

Why is there a time delay between the increase in prey and the increase in predators?

What would affect the number of hares besides the predators?

Why would the number of lynx be controlled by the number of hares?
