Question 12

Answer 1

c. It is a keystone species that modifies its natural environment by damming streams to form wetlands.

Beavers play a crucial role in their ecosystem by creating wetlands through their dam-building activities. These wetlands provide habitat for a variety of plant and animal species, help to filter and purify water, and can also mitigate flooding and erosion. The presence of beavers can have a significant impact on the overall health and biodiversity of an ecosystem.
