Section 3
Beavers are also called “ecosystem engineers.” This is because their dams have a positive impact/on plants, animals, and humans.
First,/beaver dams promote biodiversity. Once the dams are created,/the number of plants and fish/increases in the area. Then,/birds and other animals/also gather around the dam. Second,/the dams prevent large floods. When beavers build dams,/they create walls across rivers. The flow of the water/becomes slower than before. So,/the dams are like natural barriers/in the water.
In this way,/beavers contribute to ecosystems/a lot. They may be small animals,/but they make a big difference/in nature.
