Which outcome accelerates when photorespiration pathways compete with carboxylation in C3 plants under hot, dry climates?

💡 Explanation

When temperatures rise, photorespiration increases as Rubisco binds more oxygen than carbon dioxide, reducing the efficiency of the Calvin cycle because it reduces carbon fixation. Therefore photosynthetic efficiency decreases rather than enhanced because water uptake, nitrogen fixation, or chlorophyll production are not directly affected by photorespiration-related oxygen binding.
