A predator-prey relationship tends to keep the populations of both species in balance.
The number of predators increases when there is prey. The number of prey reduces when there are predators.

Use your Population Ecology notes:
The rise and fall cycle of predation is a density-limiting factor because is DOES have an effect. For example, if more prey are eaten by the predators, the prey population would decrease. On the other hand, if the population of the predator decrease, the population of the prey would increase.
A predator-prey relationship tends to keep the populations of both species in balance.
The number of predators increases when there is prey. The number of prey reduces when there are predators.
Draw a line on the graph that represents:
The deer population increases until it reaches the carrying capacity of 80 deer. This is a logistic graph.
Be sure the carrying capacity is labeled at the correct position.
