Question

Say,

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.

[AI-generated answer — Bot GPT 3.5]

One potential benefit that beavers contribute to the ecosystem as keystone engineers is by creating complex wetland habitats through the construction of their dams. These habitats support a diverse range of plant and animal species, increasing overall biodiversity in the area. If beavers were to be removed from the ecosystem, the loss of their dam-building activities could result in reduced habitat diversity and the loss of important wetland ecosystems. This could have cascading effects on the surrounding environment, impacting water quality, flood control, and the overall health of the river ecosystem.
