Predator Prey Population

The relationship between Cheetahs and zebras in Africa depicts the predator-prey relationship. Since the zebras are a main prey of the cheetah, researchers have realized a food shortage as the cheetahs are eating too many zebras. This keeps the cheetah population in check. How does this relationship affect this populations?

• The relationship controls the population size of both species

• The predator or prey will become extinct

• The predator and prey are in competition with each other

• The predator species will grow out of control.

In the following graph, the predator and prey populations change over time. What is the reason for the predator population decreasing?

• The predator eats the prey

• The prey is eaten by the predator

• The predator runs out of food when the prey population is low

• The prey survives longer when the predator population is low

Review the graph provided. What statements can be made about the significant decline in moose in the mid 1990's?

• The moose decline was a direct result of wolf decline.

• The is no way to know why the moose population dropped.

• The drop is most likely due to the declining wolf population, but more information would be needed to determine that.

• The drop is most likely due to the increasing wolf population, but more information would be needed to determine that.

Isle Royale National Park is known for the Wolf (predator) and Moose (prey) populations. Which option below best describes this relationship.
