Definitive proof of N₂ fixation is obtained using

Question

Quizplus · Accepted Answer

Using an isotope of nitrogen, 15N, as a tracer is the most definitive way to prove N2 fixation because it allows for tracking the uptake of the specific isotope and distinguishing it from other nitrogen-containing substances in the sample. This method is more precise and accurate than spectrophotometry, gas chromatography, or electrophoresis, which may not be able to distinguish nitrogen uptake from other processes or compounds.
