Autumn Leaves: Fall leaf Color

Plants make their own food. They take water from the ground through their roots. They take a gas called carbon dioxide from the air. They turn water and carbon dioxide into food using sunlight and something called Chlorophyll. Chlorophyll is green. It gives leaves their green color.
Winter days are short and dry. Many plants stop making food in the fall. The Chlorophyll goes away. Then we can see orange and yellow colors. These colors are in the leaves all Summer but the green covered them up.
