Nutrients are Released in Decay

When organisms die, their bodies decompose and nutrients are returned to the environment.
Decomposition is primarily carried out by bacteria, fungi and various detritivores. These organisms breakdown complex organic matter into simple nutrients.
Some detritivores, like earthworms, physically break down dead matter into smaller pieces, making it easier for other decomposers to process.
As organisms decay, nutrients such as carbon, nitrogen, and other minerals are released into the soil. This process is known as nutrient cycling.
Decomposition increases soil fertility by boosting its nutrient content. This encourages plant growth, contributing to the productivity of ecosystems.
Nutrient release in decay is an essential stage in the nutrient cycle. This cycle involves the transfer of nutrients in and out of organisms, soil, air and water.
The rate of decomposition can be influenced by various factors including temperature, humidity, and the presence of oxygen. Higher temperature and humidity speed up decomposition while oxygen is necessary for aerobic decomposition.
Materials that are easily broken down, such as sugars and amino acids, decay faster than more complex materials like cellulose and lignin.
Some organisms speed up the release of nutrients into the ecosystem. For instance, dung beetles help disperse nutrients by burying faeces in the soil.
The decay process can have major effects on the ecosystem. For example, when decomposition happens anaerobically (without oxygen), it can lead to the release of methane, a potent greenhouse gas.
