Certain types of trees, known as deciduous trees, have leaves which will not survive the cold of winter, and therefore, the tree withdraws useful minerals from the leaves in the fall, so that those minerals will not be lost when the leaves die and fall off the tree. It is a process of nutritional conservation. The change in the chemical composition of the leaves causes a corresponding change in color.
