During photosynthesis there is the process where chlorophyll makes the leaves turn green. As fall comes the trees stop growing and this makes the process to stop. So when chlorophyll stops running through the leaves, they start to turn different colors. Than by winter all the leaves fall off and in spring they grow back again
The leaves would change colors and fall off if the tree is a deciduous tree
senescence.
Because the leaves are dying or dead when that hapens

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.

because,they lose the chlorophyl
Leaves change color because the trunk of the tree stops sending nutrients and water and other chemicals to the leaves. In the winder, the tree keeps all the nutrients inside and doesn't have the energy to keep feeding the leaves, so they change color and die and fall off. Trees with leaves that do not change color just means that they don't have this process and are most likely in a warmer climate or survive much better in cold

know yow really cant. but Levis Chang's on their own
Deciduous trees change the color of their leaves before they fall off in autumn.
