Hm. Would a mere 'sugar substitute' cause two Hobbits who were already fully grown to increase in height? I don't think one can seperate the 'magical' component fully here. And why would Ents have a need to 'replace' photosynthesis? If their life processes were the same as ordinary trees, wouldn't they have the same access to sunlight?
Ents (and Huorns) were tree-like, but I don't see a way to explain them in purely scientific terms.
