Question

In the interaction between wolves and moose, wolves prey on moose, thereby reducing their population. Later the wolf population decreases as fewer moose are available to feed upon, thereby leading to a rise in the moose population. What does this example illustrate?

Answer 1

moved to biology

choices:

Predation can affect population size.
Competition can affect population size.
Parasitism can limit the growth of population.

notice how it mentions "wolves prey on moose, thereby reducing the population [of moose]" and "the wolf population decreases as fewer moose are available to feed upon, thereby leading to a rise in the moose population."

so wolves preying on moose is the key factor that affects the relative populations of wolves and moose. is this an example of "predation" "competition" or "parasitism"? if in doubt, please review the definitions of these three terms

Answer 2

Next time, please provide answer choices for further assistance.

A) Predation can affect population size.
B) Competition can affect population size.
