WebHowever, nitrogen can be “fixed”which means that it can be converted to ammonia (NH 3) through biological, physical, or chemical processes. Biological nitrogen fixation (BNF) is the conversion of atmospheric nitrogen (N 2) into ammonia (NH 3), exclusively carried out by prokaryotes such as soil bacteria or cyanobacteria. Biological ... WebThe NO 3− and NH 3 resulting from the nitrogen fixation process are assimilated into the specific tissue compounds of algae and plants. Animals then eat these algae and plants, incorporating them into their own body compounds. View chapter Purchase book Symbiotic nitrogen fixation☆
