Question

Use information about the moose population presented in the graph as the basis for explaining the change in the wolf population after 1980. Explain one possible reason for the change in the moose population after 1980.

Answer 1

The main reason for the increase in the population of the moose is decrease in the predation by wolves.

The wolves eat the mooses, and the presence of the wolves do not let the moose population increase, as the population of the wolves decrease, the predation of the mooses also decrease. As a result, more mosses can survive, which lead to the increase shown in the graph.
