Which metabolic consequence results because legume productivity is limited?

💡 Explanation

Low available soil phosphorus constrains ATP production, which then limits nitrogen fixation via the nitrogenase enzyme's reduction of N2 to NH3. Therefore, nitrogen assimilation rates decline, rather than enabling adequate fixation because the necessary ATP is limiting.
