Which outcome follows when nitrogenase action declines in plants?

💡 Explanation

Reduced nitrogenase activity prevents nitrogen fixation, because this enzyme complex catalyzes the conversion of atmospheric nitrogen to ammonia, therefore ammonia available for amino acid synthesis decreases, rather than increased photosynthesis via heightened xylem transport, or induced stomatal closure.
