C3 photosynthesis is limited during hot, dry weather. This is because the enzyme (Rubisco) that captures carbon dioxide in the C3 process also binds to oxygen. When the weather is hot and dry, plants close their stomata to prevent water loss. This reduces the amount of carbon dioxide that can enter the leaf and increases the amount of oxygen. As a result, Rubisco is more likely to bind to oxygen rather than carbon dioxide, leading to a process called photorespiration that can limit the efficiency of carbon fixation.

On the other hand, C4 and CAM photosynthesis have adaptations that allow them to better handle hot, dry conditions. C4 plants spatially separate carbon fixation and the Calvin cycle, which reduces the impact of photorespiration. CAM plants temporally separate these processes,
