Which limitation is imposed in hot climates due to rubisco efficiency?

A)Dehydration from evaporative water loss
B)Photorespiration increasing carbon dioxide loss
C)Reduced nitrogen fixation in root nodules
D)Decreased structural support vascular tissues

💡 Explanation

Photorespiration increases because rubisco binds to oxygen rather than carbon dioxide when CO2 concentration drops in hot climates’ closed stomata; therefore, carbon fixation decreases with photorespiration, rather than other stress responses.
