What do trees in temperate climates gain when they drop their leaves in the fall?

Well, when they drop they're leaves in the fall, they go dormant, so they don't really do much. (I live in a temperate climate, I should know.) However, during the fall, some species of trees (like the oak or hickory) produce nuts that you can collect and either eat or plant so you can enjoy more beautiful trees.

Why do leaves on a deciduous fall of in the winter?

It depends on what deciduous tree, if a cold deciduous or dry deciduous tree. Some cold deciduous trees keep their leaves for longer than usual, for different reasons: 1- Artificial light and warm weather in Autumn and Winter can cause a delay in falling leaves, because the tree reacts as if it's still in summer with long daylight hours and warm temperatures. But if it´s gets cold enough or frost is present, the leaves eventually die and fall off, but much later than they would. (some dead leves might stay on the tree, until Spring). On some trees, a few green leaves stay on the tree until new ones grow, speacilly in big cities. 2- There are some trees, like some oaks, that keep their dead leaves on until Spring, falling off before or while new ones grow again. 2-If it´s a dry-deciduous tree, it will only loose it´s leaves when it stops raining for a long period, and drought is present. If rain keeps falling sporadictly, the tree might keep it´s leaves as it´s got water to keep feeding them.
