Question

in which type of environment are plants most likely to use a c4 pathway of carbon fixation?
cold and wet
cold and dry
hot and wet
hot and dry

Explanation:

C4 plants have evolved to minimize photorespiration in hot and dry conditions. They separate carbon - fixation and the Calvin cycle in different cells, which helps them conserve water and efficiently use carbon dioxide when stomata are partially closed to reduce water loss in arid and high - temperature environments.

Answer:

hot and dry
