In the biosphere, prey represent a food source for predators. an increase in the population of prey means more food for predators, which will the predators' population. as a result, many more prey will be hunted, causing the prey population to . in response, the predator population will , resulting in an increase in the prey population. this entire cycle is an example of a feedback loop.

An increase in the population of prey means more food for predators, which will increase the predators' population. As a result, many more prey will be hunted, causing the prey population to decrease. In response, the predator population will decrease, resulting in an increase in the prey population.

The feedback loop is control of the system containing the prey and predator.

In this loop, the population of predator is directly proportional to prey but the population of prey is inversely proportional to a predators population.

As the population of prey increases, the population size of predator becomes large due to the availability of food. This inversely decreases the population of prey, as the predator do more hunt.

So the decrease in prey population results in a decrease in the predator population.
