Which physiological advantage results from cyclical operation of C4 photosynthetic pathways?

💡 Explanation

When CO2 is scarce, C4 plants employ a two-step carbon fixation process that includes PEP carboxylase, which is better than Rubisco at capturing CO2 by avoiding photorespiration, leading to advantage in competitive co2 uptake . Therefore enhanced CO2 capture results, rather than other options that depend on unrelated plant adaptations.
