the one remaining sea hare? what happened to the others?

Does photosynthesis actually require the intake of nitrogen? I ask because i dont really know, but i dont think it does... i think. I had always been under the impression that the raw materials for photosynthesis was CO2 and good old H2O. But for all i know nitrogen could be used up in an intermediate step somewhere... regardless, i would definitely be interested in whatever findings you come up with.
