Why do leaves change color in the fall?  
Chosen: Leaves change color in the fall due to a combination of factors including the decrease in chlorophyll production, which is the green pigment responsible for photosynthesis. As days become shorter and temperatures drop, chlorophyll breaks down, revealing other pigments such as carotenoids (which produce yellow and orange hues) and anthocyanins (which can create red and purple colors). Additionally, factors such as temperature, sunlight, and moisture levels can influence the intensity and timing of these color changes, leading to a spectacular display of autumn foliage.  
Rejected: Leaves change color in the fall because the weather changes. As it gets colder, the green color fades and other colors appear.<|im_end|>
