Explanation:

Beavers, the largest rodents in North America, are classed as a keystone species i.e their presence affects other organisms as well as the abiotic factors in an ecosystem. Beavers enhance the habitat quality of a particular region and make it habitable for other organisms.

• Beavers build dams that form wetlands that are home to majority of species in North America.
• They filter water from silt and increase the quality of water.
• They are "ecological indicators" i.e. they can help establish the health status of an ecosystem.
