Decomposition of organic material is basically the breakdown of the material as it rots and decays. There are two basic types of decomposition: aerobic and anaerobic.
Aerobic decomposition utilizes oxygen in the breakdown of organic material such as in the process of composting. Anaerobic digestion, also called fermentation, is the breakdown of organic matter completely absent of the presence of oxygen, as in the creation of biogas and biofuel.
Weather plays a huge part in the decomposition process. Arid conditions drastically affect the rate at which organic material breaks down.
