They help prevent erosion by controlling runoff.
they don't-they help prevent erosion
There are many things a plants roots do for an ecosystem. Plants roots help prevent erosion of soil for example.
Soil sitting alone is loose and can be succeptable to erosion by wind or water that runs over it. Plants have roots that compact the soil and hold it in place. The more plants, the more roots, the less erosion there is.
Erosion can wash away soil from plants and stunt their growth. Erosion can uproot plants and kill plants. On the other hand plants can help stop erosion.

by holding the soil in place with their roots
Plants can help prevent erosion by anchoring soil with their roots, decreasing the impact of wind and water. However, in some cases, where plants are removed or disturbed, erosion can occur more rapidly due to the lack of vegetation to protect the soil.
Plants are not typically considered agents of erosion. Instead, they can help prevent erosion by stabilizing soil with their roots.
