Question

in a forest, wolves feed on moose. the graph below shows a sudden decline in the wolf population due to the outbreak of a disease after the 1980s. what effect will this decline have on the forest ecosystem?

Explanation:

Wolves are predators of moose. A decline in wolf population reduces predation pressure on moose. Moose population will likely increase. More moose will consume more vegetation, which can change plant - species composition and may affect other herbivores and their predators in the forest ecosystem.

Answer:

The moose population will likely increase, leading to over - browsing of vegetation, which can cause changes in plant species composition and have a cascading effect on other species in the forest ecosystem.
