Community Interactions and Population Dynamics

Review the graph provided. What statements can be made about the significant decline in wolves around 1979?

• The wolf decline was a direct result of moose decline.

• The is no way to know why the wolf population dropped.

• The drop is most likely due to the declining moose population, but more information would be needed to determine that.

• The drop is most likely due to the increasing moose population, but more information would be needed to determine that.

• The wolf decline was a direct result of the moose increase.
