Question

a how are the predator and prey graph lines related to each other?

Explanation:

In a predator - prey graph, the population of prey typically peaks first. As the prey population increases, there is more food available for predators, causing the predator population to rise. Then, as predators increase and consume more prey, the prey population declines. This lack of food causes the predator population to also decline. After predators decline, the prey population has less predation pressure and can start to increase again, creating a cyclical relationship.

Answer:

The predator and prey graph lines show a cyclical relationship. An increase in prey population leads to an increase in predator population after a time - lag. As predators increase, prey population decreases, which in turn causes the predator population to decrease. Then the prey population can recover and the cycle repeats.
