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. do in 3 short sentences

1 answer

Beavers create wetland habitats through their dam-building activities, which provide homes for a variety of wildlife including fish, amphibians, and birds. The removal of beavers could result in a loss of these habitats, causing a decline in biodiversity and disrupting the balance of the ecosystem. The absence of beavers could also lead to changes in water flow and nutrient cycling, further impacting the health of the surrounding ecosystem.
