Question

What is the correct term for organisms that convert gaseous nitrogen into other nitrogen compounds that other organisms can use to produce organic material? Organisms such as some cyanobacteria convert gaseous nitrogen into other nitrogen compounds that other organisms can use to produce organic material. They are referred to as .

Answer 1

Answer: Nitrogen fixing agent

Nitrogen fixation is a biological process that converts atmospheric nitrogen into another forms of nitrogen used by plants and other organisms. Nitrogen fixation is carried out by organism referred as nitrogen fixing agents. The group of nitrogen fixing agent mainly includes many species of bacteria such as cynobacteria. These bacteria lives in symbiotic association with plants. These bacteria have the nitrogenase enzyme that makes a combination of atmospheric nitrogen with hydrogen to produce ammonia, which is further converted into other organic compounds. These organic compounds are necessary for amino acid synthesis in plants , which further helps in synthesis of proteins. These proteins are necessary for growth of plants. In return these bacteria receive nutrition from the plants through roots.
