+C3 represents the most common pathway for [Carbon Fixation](/wiki/Carbon_Fixation) in plants. During this fundamental process, carbon dioxide is initially incorporated into a three-carbon organic molecule, a crucial step for producing energy through [Photosynthesis](/wiki/Photosynthesis). This pathway dominates in temperate regions, though it is less efficient in hot, arid climates.
