Please read my statement again carefully. It states light=glucose, which is also converted to amino acids which are the building blocks of proteins. I basically said the terrestrial plants get ALL their NUTRITION from photosynthesis. Now corals on the other hand are not terrestrial and receive some of their nutrition from other sources than photosynthesis. I do not claim to know in what proportion. That would be something for someone more educated than me to tell us definitively.
As I said it is a good discussion, but who really has all the answers
