A soil ecosystem is a complex community of living organisms and their physical environment found in the soil. It includes various components such as bacteria, fungi, earthworms, and insects, all of which interact with each other and with the soil's minerals and organic matter. These organisms play crucial roles in nutrient cycling, decomposition, and soil formation, contributing to the overall health of the ecosystem. The soil ecosystem supports plant growth by providing essential nutrients and water. Healthy soil is vital for agriculture and natural habitats, as it helps maintain biodiversity and supports food production. Understanding the soil ecosystem is important for sustainable land management and environmental conservation.
