CAM plants (Crassulacean Acid Metabolism) conduct C3 photosynthesis during the day and switch to a modified form of C4 photosynthesis during the night, which allows them to conserve water in arid environments. They still use sunlight as an energy source, but have adapted their method of photosynthesis to cope with their environment.
