Question

which of the following claims is best supported by the data in the graph for the population of wolves between 1975 and ? population of wolves and moose on isle royale, 1960–2005 the population declined following depletion of food resources after a population overshoot. the population reached its carrying capacity in 1980 because there was abundant prey. the population increased exponentially when a new predator species was introduced to the island. the population declined slightly and then returned to its carrying capacity following the outbreak of a disease.

Explanation:

The graph shows fluctuations in wolf and moose populations. When the moose population (prey) increases, the wolf population (predator) has more food and also increases. As the wolf population grows, it preys on more moose, causing the moose population to decline. With less food, the wolf population then also declines. This cycle is consistent with the idea that when the population of prey over - shoots, it depletes food resources and the predator population declines as a result. There is no indication of a new predator species introduction, no clear sign of reaching carrying capacity in 1980, and no evidence of a disease - related decline in the graph.

Answer:

The population declined following depletion of food resources after a population overshoot.
