Denitrifying bacteria
A) make nitrogen available for assimilation.
B) decompose organic nitrogen compounds into nitrate.
C) decompose organic nitrogen compounds into ammonia.
D) fix nitrogen into ammonia.
E) convert nitrate into atmospheric nitrogen.
Denitrifying Bacteria
Microorganisms that convert nitrates in the soil to nitrogen gas, playing a vital role in the nitrogen cycle.
Atmospheric Nitrogen
A component of the Earth's atmosphere, making up about 78% by volume, primarily in the form of nitrogen gas (N2).
Organic Nitrogen Compounds
Chemical compounds that contain carbon and nitrogen, playing various roles in the metabolism of living organisms.

Final Answer :
E
Explanation :
Denitrifying bacteria convert nitrate (NO3-) into nitrogen gas (N2), releasing it back into the atmosphere and completing the nitrogen cycle. This process reduces the amount of nitrogen available in the soil for plants, contrasting with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that plants can assimilate.
