Nitrogen Cycle
A biogeochemical cycle that describes the transformations of nitrogen and nitrogen-containing compounds in nature.
Nitrogen Fixation
The process by which nitrogen gas from the atmosphere is converted into ammonia by certain bacteria, making nitrogen available to living organisms.
Denitrification
A microbial process occurring mostly in soil and aquatic environments, where nitrate is reduced and ultimately produces molecular nitrogen, removing it from the ecosystem.

Final Answer :
C
Explanation :
The nitrogen cycle consists of five main steps: nitrogen fixation (conversion of atmospheric nitrogen into a usable form for plants), nitrification (conversion of ammonia to nitrate by bacteria), assimilation (uptake of nitrates by plants), ammonification (conversion of organic nitrogen back into ammonia by decomposers), and denitrification (conversion of nitrate back into nitrogen gas by bacteria), making option C correct.
