Deciduous trees are defined by their seasonal cycle of shedding leaves. In the fall, these trees prepare for the winter months by losing their foliage as a way to conserve water and energy during periods when they cannot actively photosynthesize. This process is part of their natural adaptation to changing climates and seasonal variations, allowing them to survive in cooler conditions when water is less available.

Coniferous trees, on the other hand, retain their needle-like leaves year-round, which are adapted to withstand cold weather. Evergreen trees also maintain their leaves throughout the seasons, providing continuous coverage and photosynthesis. While fruit-bearing trees can be either deciduous or evergreen, the defining characteristic of shedding leaves in the fall specifically identifies them as deciduous.
