Why do Fall Leaves Change Colors?

Why do the leaves change color?

“Well that is a very interesting question Victoria!” says Mrs. Adams.  “Well we all know that trees make their food through a process called photosynthesis .  Photosynthesis requires sunlight.  In fall, there is less daylight than in the spring or summer.  This makes it hard to the trees to create their own food.  The trees will cut off all supply to their leaves and live off the food they have stored up in the spring and summer.  Leaves naturally have a yellow or orange color in them.  However the green chlorophyll , made during photosynthesis, covers up all of the other colors.  Since the trees have cut off the leaves, the chlorophyll will stop being made and the natural colors will shine through. The leaves can also turn red and brown due to excess food left in the leaves after they are cut off from the tree.”
