Question

for over 50 years, the wolf and moose populations on isle royale in lake superior served as a classic example of how predator - prey interactions limit population growth. as shown in the graph, changes in population size occur in an offset manner. in other words, it takes some time for an increase or decrease in one population to affect the other. over time, the populations rise and fall in a pattern. 1. based on this graph, what is the most likely explanation for the increase in moose population between 1989 and 1995?

Explanation:

In predator - prey relationships, when the predator (wolf) population is low, there is less predation pressure on the prey (moose). Between 1989 and 1995, the wolf population was likely low, allowing the moose population to increase due to reduced predation.

Answer:

The wolf population was low, resulting in less predation on the moose, allowing the moose population to grow.
