Question

which factors would decrease the size of the wolf population? choose all that apply.
a a large moose population
b a low moose population
c canine parvo virus
d hunting on the protected island

what would happen to the moose population if the wolves were removed from the ecosystem?
a it would remain the same.
b it would overpopulate, and then decrease due to competition for resources.
c it would decrease, and the moose would go extinct.

Explanation:

• For the first question:
• A low moose population (\(b\)) would decrease the wolf population as wolves rely on moose as a food source.
• Canine parvo virus (\(c\)) is a disease that can kill wolves, thus decreasing their population.
• Hunting on the protected island (\(d\)) directly reduces the wolf population.
• A large moose population (\(a\)) would increase the wolf population as there is more food available.
• For the second question:
• If wolves are removed, moose have fewer predators. They would overpopulate initially. But as their numbers grow, competition for resources (like food, space) would increase. This competition would lead to a decrease in the moose population.

Answer:

• First question: \(b\), \(c\), \(d\)
• Second question: \(b\)
