Soil ecosystems are vital as they support plant growth, which forms the base of most food webs. They are home to a variety of organisms, including bacteria, fungi, insects, and larger animals that contribute to soil health and fertility through processes such as decomposition and nutrient cycling. Healthy soil ecosystems improve water retention and filter pollutants, playing a crucial role in sustainability and agricultural productivity. Additionally, they contribute to carbon sequestration, helping to mitigate climate change effects.
