Question

how do beaver dams contribute to species diversity in the ecosystem? a provide access to food in winter b keep predators away from the ecosystem c provide a habitat for a variety of species d ensure that only beavers have access to water

Explanation:

Species diversity relies on available habitats. Beaver dams create ponds, wetlands, and slow-moving water—habitats for aquatic plants, fish, amphibians, birds, and mammals. Option A helps beavers but not overall diversity; B is incorrect (predators still access ecosystems); D reduces diversity. Only C directly links dams to supporting varied species.

Answer:

C. provide a habitat for a variety of species
