The nitrogen cycle is a biogeochemical cycle in which nitrogen is circulated, converted into different chemical forms, in ecosystems including the biosphere and the atmosphere. It has various steps:

Nitrogen Fixation is the first step in the nitrogen cycle in which the conversion of atmospheric nitrogen into ammonia with the help of bacteria such as Azotobacter and Rhizobium.Assimilation - involves the absorption of nitrogen compounds by the plants from the soil.Ammonification - in this step dead organic matter of plants and animals are decomposed by the soil bacteria to produce ammonia.Nitrification - Involves conversion of ammonia into nitrates by the soil bacteria Nitrosomonas and Nitrococcus.Denitrification:  a microbial process of reducing nitrate and nitrite to gaseous forms of nitrogen

Thus,

I have a chart for this if you'd like that it really helps to better understand the Nitrogen Cycle and how it works.

The National Research Act of 1974 set the stage for several important systems of checks and balances in clinical research. It led to the creation of the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research, as well as the Belmont Report and Institutional Review Boards (IRBs).

Hope This Helps!
