Which outcome occurs when soil lacks nitrates within a symbiotic nitrogen fixation system?

💡 Explanation

Legume nodule respiration declines because the rate of nitrogen fixation decreases due to the reduced presence of soil nitrates acting as the root trigger for nodule production; therefore, energy usage is lower, rather than increased, enzyme output or impacts involving any other element.
