Beavers contribute to the ecosystem by creating wetlands through their dam-building activities. These wetlands provide habitat for a variety of plant and animal species, increasing biodiversity in the area. The wetlands also help to filter and clean water, improve water quality, and reduce flooding risks.

If beavers were removed from the ecosystem, these wetlands would disappear, leading to a loss of habitat for many species that rely on them. This could result in a decrease in biodiversity and ecosystem function. Additionally, the absence of beavers could lead to an increase in erosion along riverbanks and a decrease in water quality due to the loss of natural filtration processes. Overall, the removal of beavers could have significant negative impacts on the surrounding ecosystem. put it all in 3 teen sentences

Beavers help create wetlands which provide habitat for plants and animals, increase biodiversity, and improve water quality. Without beavers, wetlands would disappear, leading to a loss of habitat, decreased biodiversity, and negative impacts on ecosystem function. The absence of beavers could result in increased erosion, decreased water quality, and overall harm to the surrounding ecosystem.
