All of the following are involved in nitrification except
Correct answer: C. Rhizohium
- A. Nitrobacter
- B. Nitrosomonas
- C. Rhizohium
- D. All of these
Explanation
Nitrification is the conversion of ammonia into nitrite and then nitrate, carried out mainly by Nitrosomonas and Nitrobacter. Rhizobium fixes atmospheric nitrogen in legume root nodules rather than carrying out nitrification. The likely alternative is d, but 'all of these' is incorrect because Rhizobium is excluded.
