Decomposition and the carbon cycle.
Revision of igcse and gcse biology. Carbon is probably the most vital element on planet earth. Decomposition is carried out by bacteria and fungi. Carbon—the element that defines life—enters the biota through photosynthesis while the oxygen released in the process makes possible aerobic carbon enters the biosphere as atmospheric carbon dioxide (co 2), which is incorporated by photosynthetic organisms into carbohydrates.
