Nitrogen returns to the atmosphere through a process called denitrification. <u>Option C.</u>
<u />
Denitrification is the process of converting nitrate to nitrogen gas thereby removing bioavailable nitrogen and returning it to the atmosphere. Nitrogen is returned to the atmosphere through the activity of organisms known as decomposers. increase. Some bacteria are decomposers breaking down the complex nitrogen compounds found in dead organisms and animal waste.
Denitrification is a microbial process that reduces nitrates and nitrites to gaseous nitrogen primarily nitrous oxide N2O and nitrogen N2. Various microorganisms can denitrify. Denitrification is a response to changes in oxygen O2 concentration in the immediate environment. Atmospheric nitrogen is utilized by certain microorganisms through a biological fixation process. Alone or in symbiotic relationships with some plants and animals microorganisms can fix atmospheric nitrogen.
