Why do leaves of the diciduouse trees t fall in the autumn?

Deciduous trees shed their leaves in autumn as a survival strategy to conserve water and energy during the colder months. As temperatures drop and daylight decreases, trees undergo a process called senescence, where chlorophyll breaks down, leading to the changing colors of leaves. This process allows the tree to reallocate nutrients from the leaves to the trunk and roots, preparing for winter. By shedding leaves, trees also reduce water loss through transpiration when water is less available in winter.
