"The lithosphere (from the Greek for "rocky" sphere) is the solid outermost shell of a rocky planet. On the Earth, the lithosphere includes the crust and the uppermost layer of the mantle (the upper mantle or lower lithosphere) which is joined to the crust."

Since all the dirt and organic material on Earth is in the lithosphere, you could say that the animals depend on the trees, but that the trees depend on the lithosphere. The roots of all trees are anchored in the topsoil (and in some cases in the subsoil), draw their water from the soil through osmosis, and get all their nutrients from the soil.
