Fall leaves are the leaves that change color and eventually fall from trees during the autumn season. This transformation occurs as temperatures drop and daylight decreases, signaling trees to prepare for winter. The vibrant colors, such as red, orange, and yellow, are due to the breakdown of chlorophyll, the green pigment responsible for photosynthesis. As leaves fall, they create a beautiful carpet on the ground, contributing to the natural cycle of decomposition. This process enriches the soil, providing nutrients for future plant growth. Many people enjoy activities like raking leaves or walking through parks to appreciate the seasonal beauty of nature.
