What is the role of the beaver in its ecosystem?
a
It is a dominant species, as it has the greatest number of individuals among all the mammalian species of its ecosystem.
b
It is a keystone species that modifies its natural environment by damming streams to form wetlands.
c
It is an endangered species as it has the least number of individuals among all the mammalian species of its ecosystem.
d
It is a foundation species and the main source of food for the natural predators of its ecosystem.
b. It is a keystone species that modifies its natural environment by damming streams to form wetlands.
Beavers play a crucial role in their ecosystem by creating habitat for other species. Their dam-building activities create wetlands that provide habitat for a variety of plants, insects, fish, and other wildlife. Wetlands are important for water filtration, flood control, and overall ecosystem health. Beavers also help regulate water flow and water levels in streams, which can benefit both aquatic and terrestrial species. In this way, beavers are considered a keystone species in their ecosystem.
