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. But make it sound like a 12 year old wrote it and only make it 4 sentences please

Beavers help make rivers better by building dams that create new ponds for animals to live in. This can make more homes for fish and birds to live in. If the beavers were taken away, the rivers might not have as many ponds, which could make it harder for some animals to find a place to live. It’s important to have beavers in the ecosystem because they help other animals have a place to call home.

Actually can you make it 3 pleaseeee

Beavers make ponds for animals to live in, which is good for the ecosystem. If the beavers were gone, there might not be as many ponds, so some animals could have trouble finding homes. It's important for the beavers to stay because they help other animals have a place to live.
