The tree would drown.
Trees require evaporation through the leaves to draw nutrient enriched water from the roots through the trunk to the leaves. Which then evaporates and causes the process to be continued.
They also require Carbon for the photosynthesis process, which trees absorb via the leaves in the form of Carbon Dioxide.
What would happen then if you took a tree which only has leaves at the top and submerged it to just under the leaves? Does the bark need to be exposed to air as well or would it just rot out like timber does?
