One potential benefit that beavers contribute to the ecosystem is that they create wetlands through their dams, which can provide habitat for various aquatic plants and animals. These wetlands also help regulate nutrient cycling, water quality, and flood control. The removal of beavers can have a negative impact on the surrounding ecosystem, as it can lead to a reduction in the creation of wetlands, reduced water retention capacity, and downstream flooding. Additionally, without beavers, the river ecosystem may undergo a significant change, impacting the biodiversity and resiliency of the ecosystem. can you put that in two sentences

Beavers create wetlands through their dams, providing habitat for aquatic plants and animals while regulating nutrient cycling, water quality, and flood control. Removal of beavers can negatively impact the ecosystem by reducing wetland creation and water retention capacity, leading to downstream flooding and changes in biodiversity.
