Soil provides a medium for plant growth by anchoring the roots, supplying nutrients, and supporting the soil food web by hosting a diversity of organisms. It also helps in regulating water flow and quality in the ecosystem, acting as a filter for groundwater and surface runoff. Additionally, soil plays a role in carbon cycling and storage, helping to mitigate climate change by sequestering carbon.

A mature soil shows three distinct soil horizons known as?

The three distinct soil horizons in a mature soil are the A horizon (topsoil), B horizon (subsoil), and C horizon (parent material). These horizons form due to the process of soil formation, where various factors such as climate, organisms, topography, and time contribute to the development of distinct layers.
