eavers, 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.

Beavers play a crucial role in creating new wetland habitats through the construction of their dams. These wetlands support a diverse range of plant and animal species, including birds, fish, and amphibians. The presence of beavers also helps to regulate water flow and reduce erosion along riverbanks. If beavers were to be removed from the ecosystem, the loss of their engineering activities could have negative consequences such as decreased biodiversity, increased sedimentation in rivers, and altered water levels that could ultimately disrupt the balance of the surrounding ecosystem.
