Question:

Above is a food chain for Yellowstone Park before the wolves were removed. What changes would you expect when wolves were removed from the park?

An _________________ in Elk population and a ____________________ in tree/shrub populations.

Answer 1

Answer: Decrease, Increase

Explanation: Wolves eat Elk which causes a decrease in Elk. A decrease in Elk causes an increase in tree/shrub because Elk eat shrubs.

Answer:

Increase   decrease

Explanation :

I think that the Elks population grew since there isn't any more predator to eat them. So the aspen trees population would drop since there would be more Elks to eat them.
