Have you ever wondered why leaves change color?  As summer ends and autumn comes, the days get shorter and shorter. The trees know to get ready for winter.
During winter, there is not enough light or water for photosynthesis. The trees will live off the food stored during the summer. The green chlorophyll disappears from the leaves, and we begin to see yellow and orange colors. Small amounts of these colors have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll.
