Which process limits photosynthesis under hot, dry conditions?

💡 Explanation

Photorespiration increases when stomata close to conserve water and CO2 decreases, therefore the oxygenase activity of Rubisco increases rather than carbon fixation limiting photosynthesis, because CO2 is needed for optimal production.
