This element is one of the most abundant elemental constituents of eukaryotic tissues and prokaryotic cell walls, and is an integral component of amino acids, proteins, and nucleic acids. Most plants obtain their nitrogen by ... 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.
WebSep 5, 2024 · Plants assimilate ammonium and nitrates, producing organic nitrogen, which is available to consumers. Decomposers, including aerobic and anaerobic bacteria and fungi, break down organic nitrogen and release ammonium through ammonification.
