After the number of wolves increased from 1970–1975, what happened to the moose population in the following years? a. the population increased. b. the population decreased. c. the population stayed the same. d. the population reached carrying capacity.

B. The population decreased.

Explanation:

If the population of wolves had a significant growth between 1970-1975 we can consider that the predator level of these animals was high, then the population of animals that are prey of these animals were at risk of decreasing and that is what happened. In the graph shown in the question above, we can see that the moose population decreased because wolves, like their predators, were in greater numbers and were able to suppress the moose population due to predatorism.
