Which of the following process involves the formation of nitrate from ammonia?
Show Hint
• NH$_3$ → NO$_2^-$ → NO$_3^-$ = Nitrification
• Key bacteria: Nitrosomonas, Nitrobacter
- Ammonification
- Denitrification
- Nitrification
- Nitrogen fixation
The Correct Option is C
Solution and Explanation
• Ammonification: Organic nitrogen → Ammonia
• Nitrification: Ammonia → Nitrite → Nitrate
• Denitrification: Nitrate → Nitrogen gas
• Nitrogen fixation: Atmospheric nitrogen → Ammonia
Step 1: Analyzing each option.
• Ammonification: Produces ammonia → Not correct.
• Denitrification: Reduces nitrate to nitrogen gas → Not correct.
• Nitrification: Converts ammonia into nitrate → Correct.
• Nitrogen fixation: Converts nitrogen gas into ammonia → Not correct.
Step 2: Selecting the correct answer.
Thus, formation of nitrate from ammonia occurs during nitrification.
