Solution
Both C4 photosynthesis and CAM photosynthesis function in plants living in hot, dry climates.
-
C4 photosynthesis: This is a process that some plants use to convert sunlight into food. It is especially efficient in hot, dry climates because it involves a mechanism that reduces water loss during photosynthesis. Plants that use C4 photosynthesis include corn and sugarcane.
-
CAM photosynthesis: CAM stands for Crassulacean Acid Metabolism. This is another adaptation to hot, dry climates. Plants that use CAM photosynthesis, such as cacti and succulents, open their stomata (pores) at night to take in carbon dioxide, which reduces water loss.
-
C3 photosynthesis: This is the most common form of photosynthesis, used by most plants. However, it is not particularly efficient in hot, dry climates because it does not have mechanisms to reduce water loss. Therefore, it is not a correct answer to this question.
