Nitrogen assimilation is the formation of organic nitrogen compounds like amino acids from inorganic nitrogen compounds present in the environment. Organisms like plants, fungi and certain bacteria that can fix nitrogen gas (N2) depend on the ability to assimilate nitrate or ammonia for their needs. Other organisms, like animals, depend entirely on organic nitrogen from their food. Web1 - Some bacteria that live in the soil fix nitrogen using the enzyme nitrogenase. Some are free-living. Others form symbioses with plants such as legumes, for instance the bacteria …
WebDec 22, 2016 · Nitrogen (N) availability is a major factor determining plant growth and productivity. Plants acquire inorganic N from the soil, mainly in the form of nitrate and ammonium.
