The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This is where nitrogen is returned to the earth as either decaying matter, humus, decaying leaves and even lightning. It is all of the pathways by which nitrogen can enter the biosphere, be converted into different compounds and ions and eventually leave the biosphere and return to the atmosphere.
