Question

the graph shows the changing populations of wolves and moose in isle royale national park. wolves are predators, and moose are their prey. which of the following pairs of populations is most likely to increase and decrease in a similar pattern to the wolves and moose? 1. moose and balsam fir, which are the favorite food plants of moose 2. male wolves and female wolves 3. very old wolves and young wolf pups 4. moose and the beneficial bacteria that live in the digestive tracts of moose

Explanation:

In a predator - prey relationship like that of wolves and moose, when the moose population increases, there is more food for wolves, so the wolf population is likely to increase. As the wolf population increases, more moose are hunted, causing the moose population to decrease. Then, with less food available, the wolf population decreases. Moose and balsam fir have a food - resource relationship where more balsam fir can support a larger moose population, which in turn can support more wolves.

Answer:

Moose and balsam fir, which are the favorite food plants of moose
