The correct option is C Denitrification
The correct option is C.
Explanation of the correct option :
- The nitrogen cycle is the recycling phase of the nitrogen, which includes nitrogen fixation, ammonification, nitrification, and denitrification.
- Denitrification is the process through which the nitrates and nitrites are converted back to atmospheric nitrogen.
Explanation of the incorrect option:
Option A:
Ammonification is the process where microscopic organisms like bacteria or other types of decomposing organisms break down nitrogen-containing chemicals from dead organic matter, into simple substances like ammonia.
Option B:
Nitrification is the process by which ammonia is converted into nitrite and then to nitrate by nitrifying bacteria.
Option D:
Nitrogen assimilation is the process by which inorganic nitrogen compounds are used to form organic nitrogen compounds such as amino acids, amides, etc.
Final answer: In the nitrogen cycle, atmospheric nitrogen is fixed by bacteria and converted into ammonia. Ammonia is further converted into other forms of nitrogen. At the end of the cycle, nitrogen is returned to the atmosphere by the process of Denitrification.
