Why do trees lose their leaves in the winter?

Trees lose their leaves in the winter as an adaptation to conserve water and energy. During colder months, many trees enter a state of dormancy, reducing their metabolic activity. Deciduous trees, in particular, shed their leaves to prevent water loss through transpiration, as the frozen ground makes water less accessible. The process also helps protect the tree from the weight of snow and ice accumulating on the leaves. This adaptation allows trees to survive harsh winter conditions and conserve vital resources for the next growing season.
