Wired Faculty App

Among the ecosystem services are control of floods and soil erosion. How is this achieved by the biotic components of the ecosystem ?

Solution

The biotic components like plants control floods and soil erosion. The roots of the plants hold the soil and prevent soil erosion. Roots also make the soil porous and allow the infiltration of water, hence preventing floods. Dense forests slow down the water flow and keep a check on the floods and soil erosion.
