Question:
Why do deciduous trees shed threir leaves before winter unlike evergreen conifers? Surely this is a waste of resources.


Replies:
An adaptation for the winter cold, snow, and low soil available water. They do reallocate much of the resources (e.g., nutrients in sap downward) before leaf fall.
