Leaves of an oak tree fall off during summer because the oak tree is trying to save the water and minerals of the tree. i.e. the tree is trying to reduce the amount of transpiration which takes place through heavy sunlight. So by getting rid of leaves the amount of transpiration reduces and the oak tree won't die.
I would say summer, because in spring, the leaves are just starting to grow. In fall, the leaves change color and fall off. In winter there are no leaves. In summer the leaves have all grown back and are prospering.
maple trees colour are green in spring and summer while in fall there colours are red and orange
They grow in spring from buds. They stay green in summer. They fall off in autumn. They rot down and worms eat them. The tree is bare in winter.
The leaves lose chloroplasts as summer turns to fall.
No, it drops its leaves in winter. BTW no leaves are ever-green: they all fall off sometime. But some trees of bushes are evergreens. They remain green in winter.
The trees lose the chlorophyll, revealing their natural colors. chlorophyll is the pigment which makes leaves and plants green.
Deciduous trees fall in the Fall. The trees lose their color and lose their leaves. That's why there are many trees that are bare in the Fall.

Yes the leaves fall on trees like pecan, oak, sycamore, and other types of trees. Pine, and cedar wont change at all from spring, summer, fall and winter. Not sure about more southern parts of Florida where orange and palm trees flourish.
Autumn which is also called "fall" because the leaves fall from the trees.
