The correct response is "Chlorophyll breaks down because there's less sunlight."
The correct answer is: Chlorophyll breaks down because there's less sunlight.
Explanation:
During the fall season, the days become shorter and there is less sunlight available for photosynthesis. Because of this, trees start preparing for winter by shutting down their food-making process. Chlorophyll, which is responsible for the green color of leaves, breaks down under sunlight, revealing other pigments that were previously masked. As a result, the red, orange, and yellow pigments that were present in the leaves all along become more visible and give the leaves their vibrant fall colors.
