A large number of breeding birds in Yellowstone nest and feed in stands of aspen, willow and cottonwood. How do you think the return of the wolf will impact these populations?

The correct answer is - By increasing tree abundance, wolves will indirectly boost bird population sizes.

Explanation:

The return of wolves certainly affects the population of the birds but not directly as wolves not prefer birds as their prey and looks for the larger prey, however, they also hunt birds but when they did not get their preferred prey. Due to the wolves, there would be more space for nests in those increased trees.

Thus, the correct answer is - By increasing tree abundance, wolves will indirectly boost bird population sizes.

i believe the answer is a or 1

the median of the data is 4.5.
