In a process called ______, bacteria and archaea convert ammonium to nitrate, which can be taken up by plants and other autotrophs; organic matter is broken down by ______, which returns nitrogen to the abiotic environment.Multiple choice question.decomposition; nitrogen fixationnitrification; decompositiondenitrification; transpirationnitrogen fixation; 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-).

Select the drop down to complete each sentence.Within the nitrogen cycle, the process of nitrogen fixation is where bacteria remove .Nitrification refers to the process where bacteria oxidize .The assimilation process is where plants absorb .During ammonification, decomposers convert .Finally, denitrification refers to the process where bacteria convert .

Nitrogen fixation:Question 21Select one:a.is carried out by certain types of bacteria.b.cannot occur in plants without nitrogen-fixing bacterial symbionts.c.changes nitrogen to a form called nitrates.d.all of the above

Which of the following best describes the process of nitrogen fixation in the nitrogen cycle?*1 pointConversion of nitrogen gas into ammonia by nitrogen-fixing bacteriaConversion of nitrates into nitrogen gas by denitrifying bacteriaConversion of ammonia into nitrates by nitrifying bacteriaAbsorption of nitrogen compounds by plants through their roots
