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 2 to 4 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. make the words simple and max 70 words and make it sound like a 7th grader wrote it

Beavers help make homes for other animals by building dams and ponds. These homes provide food and shelter for fish, birds, and insects. If beavers were removed, the river ecosystem could change a lot. There would be less diversity of plants and animals, and the river might not flow as well.
