Question

Match List-I with List-II 



Choose the correct answer from the options given below:

• (A) (I), (B) (II), (C) (III), (D) (IV)
• (A) (II), (B) (III), (C) (IV), (D) (I)
• (A) (I), (B) (II), (C) (IV), (D) (III)
• (A) (III), (B) (IV), (C) (I), (D) (II)

Hint:

Ammonification = organic nitrogen to ammonium, Denitrification = nitrate to nitrogen, Nitrification = ammonia to nitrate, Nitrogen fixation = atmospheric nitrogen to ammonia.

Answer 1

The Correct Option is B

- Ammonification (A): The conversion of organic nitrogen (from dead organisms) into ammonium (NH\(_4^+\)) is called ammonification.
- Denitrification (B): The process where nitrate (NO\(_3^-\)) is reduced to nitrogen gas (N\(_2\)), releasing it into the atmosphere.
- Nitrification (C): The conversion of ammonia (NH\(_3\)) into nitrate and nitrite by nitrifying bacteria.
- Nitrogen fixation (D): The process of converting atmospheric nitrogen (N\(_2\)) into ammonia (NH\(_3\)) by nitrogen-fixing bacteria.
Step 2: Conclusion.
Thus, the correct matching is: \[ \text{(A) (II), (B) (III), (C) (IV), (D) (I)} \]
Final Answer: \[ \boxed{\text{(A) (II), (B) (III), (C) (IV), (D) (I)}} \]
