Question
In nitrogen fixation, the reduction of nitrogen gas to ammonia occurs due to the activities of: a. Haber's process b. Thunderstorm c. Nitrogen fixing bacteria d. Decomposers
Correct Answer
Option C is the correct answer.
Detailed Explanation
Biological nitrogen fixation is carried out by specialized microorganisms called nitrogen-fixing bacteria (e.g., Rhizobium in root nodules, free-living Azotobacter). They possess the enzyme nitrogenase, which converts N2 to NH3.
Hint
These tiny organisms have the special power to pull nitrogen from the air.
