Sorry, but photosynthesis is considered the trees life source.

A Tree From the Air?
So where does all the food come from that the tree uses to grow? The
answer is simple yet very complex - it comes from the air. Trees like
all plants carry on the process of photosynthesis. Photosynthesis is
the process by which plants utilize the energy from the sun to make
sugar from carbon dioxide in the air. The next time you look at a
tree think about the fact that what you see was once nothing but a
bunch of carbon dioxide gas. The general equation for photosynthesis
is pretty simple:
Sun light
CO2(carbon dioxide) + H20 (water) ----> C6H12O6 (sugar) + O2(oxygen)
This simple equation reveals much about a plant.
First its obvious they need sunlight to survive.
