Question

1. what happened to the amount of biodiversity in yellowstone when the wolves were reintroduced? 1 point a) the amount of biodiversity decreased. b) the amount of biodiversity increased. c) the amount of biodiversity stayed the same.

Explanation:

When wolves were reintroduced to Yellowstone, they regulated the elk population (a primary prey). This led to changes in vegetation (e.g., trees like willows and aspens could grow as elk browsing decreased), which supported more species (e.g., beavers, birds, insects). The trophic cascade effect increased the variety and number of species, so biodiversity increased.

Answer:

B) The amount of biodiversity increased.
