decomposerIn biology, any organism that breaks down dead matter. Decomposers play a vital role in the ecosystem by freeing important chemical substances, such as nitrogen compounds, locked up in dead organisms or excrement. They feed on some of the released organic matter, but leave the rest to filter back into the soil as dissolved nutrients, or pass in gas form into the atmosphere, for example as nitrogen and carbon dioxide. The principal decomposers are bacteria and fungi, but earthworms and many other invertebrates are often included in this group. The nitrogen cycle relies on the actions of decomposers. |
