Question

Nitrogen Cycle explanation

Answer 1

1.Nitrogen is present in the environment in a wide variety of chemical forms including organic nitrogen, ammonium , nitrite , nitrate , nitrogenous oxide, nitric oxide  or inorganic nitrogen gas. 
2.Organic nitrogen may be in the form of a living organism, humus or in the intermediate products of organic matter decomposition.
3.The processes of the nitrogen cycle transform nitrogen from one form to another. Many of those processes are carried out by microbes, either in their effort to harvest energy or to accumulate nitrogen in a form needed for their growth.
4.For example, the nitrogenous wastes in animal urine are broken down by nitrifying bacteria in the soil to be used as new. The diagram besides shows how these processes fit together to form the nitrogen cycle.
