Beavers kill trees by cutting them down. they then use these trees to dam streams. they also in creating ponds. this increases the biodiversity of the place because it modifies the distribution and population of many plants and animals. which type of species are beavers?

Engineers

Explanation:

Beavers are called ecosystem engineers by ecologists because the change their ecosystem by cutting trees present in their ecosystem and make dams over the river by these trees, dig channels and build lodges.

These dams alter the river flow and results in the formation of a lake which have still water. Over time many still water-loving animals and plants occupy the ponds and make a new ecosystem in that area. So by making dams beavers helps in increasing the biodiversity of the place.

So due to the capability of beavers to bring change in its ecosystem, they are called ecosystem engineers.
