It is very energetically expensive for a tree to carry out photosynthesis in the winter, when there is often little sunlight and freezing temperatures make water transport (from the ground into the tree’s trunk and leaves) a problem. So it’s more energy efficient for a leafy tree to close down operations in the winter and go dormant.
During winter, light, heat, water and minerals become less available. The plants then begin to get rid of the leaves by discontinuing the flow of food to leaves. And once the supply of food to leaves is closed off, these leaves begin to change their colour and with the passage of time fall off.
