Q

Describe and explain a predator-prey graph

A

When the population of the prey increases, the population of the predator increases.

When the population of the prey decreases, the population of the predator decreases.

When the population of the prey is high, the population of the predator increases.

This makes the number of prey decrease, which makes the population of the predator decrease and the cycle starts again.
