The Short Answer

* The mass from the leaves comes, in part, from the soil. The leaves later become soil, round and round. * The leaves compact down a fair bit. Imagine a big pile of leaves, now dry them, shred them and squash them all down. You'll get a surprisingly small amount. * Decomposing lets some of the mass escape as gas. * Soil can be eroded via rain and wind. Plants also grow faster than soil rises, which helps. It takes a long time for that to change normally so unless you've a very old tree you wouldn't notice.
