In some ecosystems, wolves have been eliminated due to their threats to humans. How can the reintroduction of wolves benefit the ecosystem?

• It can eliminate weak animals from a prey population, thereby decreasing competition for natural resources

• It can eliminate the most fit animals among the prey population, which will cause an increase in birth rates of the prey

• It can cause the prey population to migrate to other areas, resulting in more fit prey.

• It can cause the prey population to better blend in with their environment.
