Sample Response: Leaf color comes from three pigments: chlorophyll, carotenoid, and anthocyanin. Chlorophyll is the pigment that makes leaves green and allows plants to make their own food using sunlight, water, and carbon dioxide. In the autumn, trees stop producing chlorophyll because there is less sunlight available. This allows carotenoid to show through, making the leaves yellow, orange, and brown. This is an example of a chemical change. What did you include in your response? Check all tha
