Many goodies in here, but especially:

A correlation was found between phosphate uptake rates and the organic or inorganic feeding history of the corals; rates were indeed 4.6 times higher in 8-week starved than in fed corals and depended on the repletion status of phosphorus stocks within the symbionts.

And…

We report evidence showing that zooxanthellae act as a sink of phosphate within the symbiosis.
