Question

In which one of the following processes are the bacteria {Nitrosomonas, {Nitrosococcus} and {Nitrobacter} involved?

• A. Denitrification
• B. Deamination
• C. Eutrophication
• D. Nitrification

Hint:

Nitrification occurs in two steps: ammonia to nitrite and nitrite to nitrate.

Answer 1

The Correct Option is D

Step 1: Understanding nitrification.
Nitrification is a biological oxidation process in which ammonia is converted into nitrite and then nitrate by nitrifying bacteria.
Step 2: Analyzing bacterial roles.
Nitrosomonas and Nitrosococcus convert ammonia into nitrite.
Nitrobacter converts nitrite into nitrate.
Step 3: Conclusion.
Since all these bacteria participate in nitrification, the correct answer is (D) Nitrification.
