Decay is the process of recycling the elements back to the start of the food
chain. As all living things are made of materials such as carbon, oxygen,
nitrogen. These molecules are then converted into other molecules for
storage. Before the organisms die, these materials are then returned through
waste products, which are broken down by microorganisms.
Microorganism also breaks down organisms, when they die therefore
ensuring all the molecules return back either into the soil or into the air
Microorganisms also work best when the conditions are warm and moist,
as the enzymes work quicker in hotter conditions and the moist environment
provides the organisms with the nutrients to survive. All the important
elements such as carbon are recycled so they can be put back into the soil
and be used by plants and enter the food chain again.
