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

(N/A) The biotic components of an ecosystem include living organisms such as plants and animals. Plants play a crucial role in controlling floods and soil erosion.
$1$. Soil Erosion Control: The root systems of plants bind soil particles together,which prevents the topsoil from being washed away by running water or blown away by wind.
$2$. Flood Control: Roots increase the porosity of the soil,which enhances the infiltration of water into the ground. This reduces surface runoff,thereby preventing floods.
$3$. Additional Benefits: By maintaining soil structure,plants also improve soil fertility and support biodiversity,which further stabilizes the ecosystem.
