Science glossary film: Decomposition

The process by which dead organic matter is broken down into simpler chemicals and dispersed. It's an essential part of healthy ecosystems, as there is only a finite amount of organic material within any living system that must be constantly recycled to support new organisms and new growth. Decomposition normally requires decomposing bacteria and fungi, warmth, moisture and oxygen.
