Some bacteria and archaea can convert atmospheric nitrogen (N2) into a usable form through a process calledMultiple choice question.nitrogen fixation.decomposition.denitrification.nitrification.

Nitrogen fixation is the process in which some bacteria and archaea convertMultiple choice question.nitrogen gas (N2) into ammonium ions (NH4+).nitrate (NO3-) into nitrogen gas (N2).ammonium ions (NH4+) into nitrogen gas (N2).ammonium ions (NH4+) into nitrate (NO3-).

Nitrogen is an essential part of the proteins and DNA of organisms. Although nitrogen gas makes up about 78% of Earth’s atmosphere, it is unavailable for use by organisms in its gaseous form. Only when nitrogen is absorbed by beneficial bacteria in the roots of legumes does it enter the pathways that carry it through biological communities.The processes of conversion of atmospheric nitrogen first into ammonium ions (NH4+) and then into nitrates (NO3–) are called respectively*1 pointnitrogen fixation and denitrificationnitrogen fixation and nitrificationammonification and nitrificationammonification and denitrification
