The fall leaf life cycle starts with the end of summer and the shortening of the days. As the days get shorter, the tree does not have enough sunlight to make food for itself. Rather than struggle to make food through the winter, it shuts down. It stops producing chlorophyll and allows its fall leaves to die.
