Conversion of ammonia or ammonium ion into nitrites during nitrogen cycle occurs due_____________?
Correct answer: B. Nitrosomonas
- A. Rhizobium
- B. Nitrosomonas
- C. Nitrobacter
- D. Pseudomonas
Explanation
Nitrosomonas carries out the first nitrification step, oxidizing ammonia or ammonium ions into nitrites. Nitrobacter performs the next step by converting nitrites into nitrates, so students may choose c when they reverse the two bacterial stages.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
