Why Do Some Trees Lose Their Leaves In Winter?

Just like animals hibernate in winter, it is also a similar case with some trees.  Specially trees with broad-bladed leaves lose their leaves during the period of winter.  This is a rest period for trees and as a result they don't require food in this period of still tranquillity.  So the leaves, which actually are the main source of manufacturing the food for plants and trees are not needed during this period and as a result the trees shed those leaves.  Such trees are termed as deciduous trees, a word which is derived from the Latin word 'decidere', which means to fall.  These type of trees shed all their leaves and become bare during the cold weather.  As for when summer comes or a warmer climate arrives, they become evergreen again, developing new leaves for making their food.

The deciduous trees grow in the deciduous belt of the earth, which is a region that is not too harsh in either summer or winter and has a temperate climate, where the summers are warm and not hot and the winters are cool and not cold.
