Why deciduous trees shed their leaves?

For what reason does deciduous trees shed their leaves in autumn, however conifers don't shed their needles?

Deciduous trees lose a great amount of water through evaporation from their substantial and thin leaves. In summer, this does not represent an issue, since the roots absorb enough water from the dirt, yet in winter this isn't conceivable because the soil is frozen. On the off chance that the leaves are not shed before winter, the water will proceed to evaporate and the plant will become dry up. In addition, the leaves can become fragile with frost and crack. Accordingly, the deciduous trees shed their leaves as a careful step. Interestingly, the needles of the conifers are leathery and little, and there is very little evaporation through them. The needles are likewise frost-proof and stop their development in winter.
