← Nature & AnimalsWhich 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.
