Question Beavers, large members of the rodent family in North America, are often referred to as “ecosystem/keystone engineers” by wildlife managers. Ecosystem engineers are described as animals that create, alter, or destroy a habitat. Beavers contribute to river ecosystems by bringing down old and dead trees along riverbanks. They use these trees to make their dams. Although these dams are primarily used for protection and food storage, scientists report that these dams change the surrounding environment in different ways. Given this information, in three to five sentences, describe a potential benefit that beavers contribute to the ecosystem as keystone engineers and describe a plausible impact that the removal of beavers could have on the surrounding ecosystem.

Answer 1

Beavers help create new habitats for other animals by building their dams. The dams also help to regulate water flow, which can prevent flooding and erosion in the surrounding area. If beavers were removed from the ecosystem, it could disrupt the balance of the river ecosystem, leading to potential increases in flooding and erosion. This could also impact the availability of food and shelter for other animals that rely on the beaver dams for habitat.
