Question

Which of the following is the best explanation for why extinctions are more likely with longer growing seasons in this simulation of Isle Royale? With more plants available.. moose are healthier on average and can avoid wolves, leading to extinction of the wolves. larger populations of moose and wolves are more vulnerable to environmental fluctuations, increasing the chance of extinction. there is not enough room for moose to move around the island looking for food, leading to extinction of the moose and then the wolves. moose and then wolf populations grow larger during cycle peaks-with enough wolves, all moose are eaten, leading to extinction for both.

Explanation / Answer

The location of Isle Royale provides unique oppurtunity to study the prey-predator relationship. The prey here is moose and the predatoris wolf. Wolves catch moose which are slower in moving. Moose feed on plants.When enough plants are available, moose becomes healthier and avoid being eaten by wolves. The peak in moose population occur gradually decreasing the plant population. When the plants are available less, moose become unhealthier and they are predated upon by wolves. Since large number of moose are available,the population of wolves will surge. Then,due to decline in moose population, the wolf population also decrease. Therefore, the corrct answer for this question is option 4, moose and then wolf population grow larger during cycle peaks - with enough wolves, all moose are eaten, leading to extinction for both.
