Autumn colours

There is a miraculous change in the color of the leaves every year in the fall season. They turn from green into brilliant shades of yellow, orange, red, and gold. Sometimes you can see several shades on the same leaf. But how these changes happen, and what is going on in the plant?
Read this explanation and you will understand!
Plants make their own food. They take water from the ground through their roots. They take a gas called carbon dioxide from the air. Then, they turn water and carbon dioxide into food using sunlight and something called chlorophyll. This one is green and it gives leaves their green color.

 Many plants stop making food in Autumn. Then, the chlorophyll goes away. Then, we can see different colours as orange, yellow, red, gold and also brown. When they are brown, it comes from wastes left in the leaves.
