Q. Which of the following reaction shows nitrogen fixation?
A) $2NH_{4} + 2O_{2} + 8e^{-} \rightarrow N_{2} + 4H_{2}O$
B) $2NH_{3} \rightarrow N_{2} + 3H_{2}$
C) $N_{2} + 4H_{2} \rightarrow 2NH_{3}$
D) $2N_{2} +$ Glucose $\rightarrow$ 2 Amino acids
Explanation
During the conversion of nitrogen, cyanobacteria first converts nitrogen into ammonia and ammonium. Plants can use ammonia as a nitrogen source $N_{2} + 4H_{2} \rightarrow 2NH_{3}$
