- (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)
Show Solution
The Correct Option is B
Solution and Explanation
- Ammonification (A): Organic nitrogen from dead organisms is converted into ammonium (\(NH_4^+\)).
- Denitrification (B): Nitrate (\(NO_3^-\)) is reduced to nitrogen gas (\(N_2\)), which is then released into the atmosphere.
- Nitrification (C): Ammonia (\(NH_3\)) is converted into nitrate and nitrite by nitrifying bacteria.
- Nitrogen fixation (D): Atmospheric nitrogen (\(N_2\)) is converted into ammonia (\(NH_3\)) by nitrogen-fixing bacteria.
Step 2: Conclusion.
The correct match is: \[\text{(A) (II), (B) (III), (C) (IV), (D) (I)}\]
Final Answer: \[ \boxed{\text{(A) (II), (B) (III), (C) (IV), (D) (I)}} \]
