iv.Nitrate ion

Question

Quizplus · Accepted Answer

The correct sequence of steps in nitrogen fixation is as follows:
i. Nitrogen gas
ii. Ammonia
iii. Nitrite ion
iv. Nitrate ion
During nitrogen fixation, nitrogen gas is converted into ammonia by nitrogen-fixing bacteria. Ammonia is then oxidized to form nitrite ions, which are further oxidized to form nitrate ions. Therefore, the correct sequence is i, iii, ii, iv. Among the given choices, only option C matches with the correct sequence.
