Decomposition is a research area in environmental science and biology that focuses on the breakdown of organic matter by microorganisms and other organisms. This process plays a crucial role in nutrient cycling and ecosystem functioning. Researchers in this area study the factors that influence decomposition rates, such as temperature, moisture, and the availability of nutrients. They also explore the role of decomposers, such as bacteria, fungi, and insects, in breaking down organic matter and releasing nutrients back into the soil. Understanding decomposition can help inform conservation and management practices aimed at maintaining healthy ecosystems.
