How do corals get food?
user
Most corals are photosynthetic, which means that they convert sunlight into sugars that they then use for food.  Many corals also have tentacles, so they’ll sometimes go out to hunt for plankton.  But most of the time, the coral can get all the food it needs by photosynthesizing, or by eating what’s already attached to its body.

What is their relationship to zooxanthellae
user
The zooxanthellae live inside the coral, and help it by providing sugars that are derived from the food the coral eats.  The zooxanthellae themselves get everything they need from the coral, including sunlight and sugar, and also help the coral stay healthy by removing harmful waste products.
