As summer ends and autumn comes, the days get shorter and shorter. The trees "know" that they have to be ready for winter. During winter, there is not enough sunlight or water for the photosynthesis process. The trees will rest, and use the food that they have stored during summer. The trees begin to close their food factories. The green chlorophyll substance disappears from the leaves. As the leaves begin to lose their green colour, they change into beautiful yellow and orange.
In some trees, like maple tree, glucose is trapped in the leaves after the photosynthesis process stops. Sunlight and cool rights turn the green colour of the leaves into red. Oak leaves become brown because of wastes that are left in the leaves. This combination of red and brown makes the trees look very beautiful in autumn.
