In the Summer, trees have plenty of light and water, but as autumn comes, the days shorten and they loose the ability to produce enough light and water for photosynthesis.
Photosynthesis is process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Basically, the trees are able to live off of the food that is stored up from the summer. The color green will begin to change to either a yellow, red, or orange depending on the type of tree. What a gorgeous sight to see!!!
