Question

Arrange the given processes involved in the nitrogen cycle:
(A) Ammonia formation
(B) Organic nitrogen formation
(C) Soil organic nitrogen formation
(D) Nitrate formation
Choose the correct answer from the options given below:

• A. (A), (B), (C), (D)
• B. (A), (B), (D), (C)
• C. (B), (A), (D), (C)
• D. (B), (C), (A), (D)

Hint:

Understand the sequence of nitrogen transformation processes in the nitrogen cycle.

Answer 1

The Correct Option is D

The correct sequence of processes in the nitrogen cycle is:
1. Organic nitrogen formation: Ammonia is assimilated into organic molecules.
2. Soil organic nitrogen formation: Organic nitrogen is converted into soil organic matter.
3. Ammonia formation: Atmospheric nitrogen is converted into ammonia.
4. Nitrate formation: Ammonia and organic nitrogen are oxidized to nitrates.
