D The wolf carrying-capacity rises as moose populations increase, but with a delayed effect.
This conclusion can be drawn from the data presented in the graph, which shows that as moose populations increase, wolf populations also increase, but with a delay. This is indicative of the fact that the availability of food source (moose) affects the carrying capacity of the wolves on the island, leading to fluctuations in their populations.
The graph shown above is from one of the most well-known and on-going ecological studies ever performed. Isle Royal National Park, an island on Lake Superior, keeps data of populations of wolves and moose living there. The moose are a major food source for the wolves.
Analyze the graph data to conclude how the moose population affects the population of wolves.
