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

Answer»

Ecosystem services regulate and protects ecosystem that are essential for maintaining climate and ecology of area. Control of soil erosion

  • Plant roots hold soil particles firmly.
  • Plant cover protects soil from erosion by wind and water.
  • Plants increases porosity and fertility of the soil.

Control of floods It is carried by retention of water and prevention of runoff. Litter and humus of plants acts as sponge to retain rainwater. Plants hold soil, so prevents soil erosion. Rainwater does not run – off, so prevents flood as they filter water into soil.
