Studying soil organisms is important for understanding ecosystem health because these organisms play vital roles in nutrient cycling, soil formation, and organic matter decomposition. Healthy soil is critical for agricultural productivity and supports plant growth, which in turn sustains entire food webs. Soil organisms, including bacteria, fungi, and invertebrates, enhance soil structure and fertility, influencing water retention and quality. They also help regulate greenhouse gas emissions. By studying these organisms, we can devise better land management practices that promote soil health, ensuring the sustainability of agricultural systems and protecting valuable ecosystem services essential for human survival.
