Which mechanism decreases water loss during the day in a desert CAM plant?

💡 Explanation

Stomata closing during the day facilitates crassulacean acid metabolism; because CO2 fixation occurs at night with open stomata and stored for daytime photosynthesis; therefore water loss is reduced, rather than increased uptake or surface improvements.
