In a forest, wolves feed on moose. The graph shows a sudden decline in the wolf population due to the outbreak of a disease after the 1980s.
What effect did this decline have on the forest ecosystem?
A.
There will be more competition among the moose for food.
B.
There will be less competition among the moose for food.
C.
The moose population will increase indefinitely.
D.
The wolf population will compete more for food.
The correct answer is B. There will be less competition among the moose for food.
With the decline in the wolf population, there will be fewer predators hunting and feeding on the moose. As a result, there will be less pressure on the moose population, leading to a decrease in competition for food among the moose.
