Assimilation-process by which plants or animals convert nutrients into usable organic compounds, such as proteins
Denitrification-process by which certain bacteria convert nitrates into nitrogen gas
Nitrification-process by which certain bacteria convert ammonium into nitrates
Nitrogen Fixation-process by which certain bacteria in the soil convert nitrogen gas into ammonia and ammonium
