What does "deciduous" mean?

The word "deciduous" refers to trees or shrubs that shed their leaves annually, usually in the autumn, before entering a dormant period. The mental image is of a forest floor blanketed in colorful, fallen leaves as the trees prepare for winter by conserving energy. In common usage, it is often contrasted with "evergreen." While primarily used in botany, it is also applied to other biological parts that fall off after a certain period, such as "deciduous teeth," which are the primary or "baby" teeth that fall out to make room for permanent ones.
