The wolves and moose of Isle Royale are the focus of the longest-running study of a predator-prey system in the wild. Both are recent arrivals to Isle Royale: moose swam to the island in the early 1900’s. Wolves followed decades later, traveling over the ice from Canada in the 1940’s.About 40 years into the study, the wolf population crashed when humans introduced the canine-parvovirus. Additional factors over the years have impacted both populations. At one point during the study, the moose population collapsed during the most severe winter on record followed by an outbreak of moose ticks. What point on the graph represents the outbreak of moose ticks and a drastic decline in the moose population?
A) Point A
B) Point B
C) Point C
D) Point D

Respuesta :

Point C is the answer

Answer:

We have been given two cases of Wolves and moose of Isle Royale

We need to tell the outbreak of moose ticks and a drastic decline in the moose population.

We can see from the graph that A and B are representing Wolves

So, Option A and B are discarded.

Now, we should know the meaning of Outbreak in a graph which means  that the large number of people are represented by a single point.

Point C is representing large number of people at one point

So, Outbreak of Moose ticks is represented by Point C.

Now, the drastic decline is the point where the curve started to decrease

At point D the curve is decreasing

Hence, the drastic decline is at the point D.
