The Real Reason Leaves Change Color in the Fall

In autumn, leaves change color as chlorophyll breaks down, revealing yellow and orange pigments. Deciduous trees recycle nutrients from leaves before shedding them to conserve resources. Chlorophyll breakdown is managed to prevent damage from reactive oxygen. Some trees produce red pigments for protection. This process helps trees recover nutrients for new growth in spring.
