The process of decay in living organisms is commonly called decomposition. This natural process involves the breakdown of organic matter, facilitated by decomposers such as bacteria, fungi, and other microorganisms. Decomposition plays a crucial role in nutrient cycling, returning essential nutrients back into the soil, which supports new plant growth. During this process, complex organic compounds are broken down into simpler substances, ultimately contributing to the health of ecosystems. Additionally, decomposition can be influenced by factors such as temperature, moisture, and the nature of the organic material.
