What is a major consequence of soil erosion on ecosystems?

Soil erosion significantly impacts ecosystems, particularly through the depletion of nutrients. As soil is eroded, the top layer, which is rich in organic matter and essential nutrients, is often removed. This topsoil is critical for plant growth, as it contains the nutrients that plants need to thrive, such as nitrogen, phosphorus, and potassium. The loss of these nutrients can lead to poorer soil fertility, hindering plant development and reducing agricultural productivity.

Furthermore, when nutrient-rich topsoil is lost, it can upset the balance of local ecosystems, leading to reduced plant diversity and affecting the wildlife that depends on these plants for food and habitat. The erosion process can also result in sedimentation in nearby waterways, further affecting aquatic ecosystems and degrading water quality.
