What are the disadvantages of a CAM plant?

A CAM (Crassulacean Acid Metabolism) plant has several disadvantages, including reduced growth rates due to limited photosynthesis during the day when stomata are closed to minimize water loss. This adaptation can lead to lower biomass production compared to C3 or C4 plants in favorable conditions. Additionally, CAM plants may struggle in environments with high water availability, as their specialized adaptations are unnecessary and can hinder their competitiveness. Lastly, their reliance on nighttime carbon fixation can make them less efficient in rapidly changing environmental conditions.
