Ecosystem services refer to good or benefits that we get from the ecosystem. Prevention of soil erosion and floods comes under benefits provided by the ecosystem to us. The ecosystem includes both abiotic and biotic components. The biotic components are the living organisms present in an ecosystem. Biotic components play a role in providing ecosystem services. some of these roles are as follows:

1. The roots of plants hold the soil particles very tightly. This prevents the erosion or degradation of the top layer of soil

2. Plants increase soil fertility and biodiversity.

3. Presence of plants also help in controlling the flow of floods and lead to minimal destructions. 

4. roots of plants make the soil porous thus allowing water to seep in the soil.

5. The carbon dioxide and oxygen balance are maintained in the ecosystem via plants and animals.
