What do coral polyps feed on?
The algae live within the coral polyps, using sunlight to make sugar for energy. This energy is transferred to the polyp, providing much needed nourishment. In turn, coral polyps provide the algae with carbon dioxide and a protective home. Corals also eat by catching tiny floating animals called zooplankton.
Does Coral produce oxygen?
Most corals, like other cnidarians, contain a symbiotic algae called zooxanthellae, within their gastrodermal cells. … In return, the algae produce oxygen and help the coral to remove wastes.
What do coral polyps need to survive?
What Do Coral Reefs Need to Survive?Sunlight: Corals need to grow in shallow water where sunlight can reach them. … Clear water: Corals need clear water that lets sunlight through; they don’t thrive well when the water is opaque. … Warm water temperature: Reef-building corals require warm water conditions to survive.More items…

Corals are animals, though, because they do not make their own food, as plants do. … Most structures that we call “coral” are, in fact, made up of hundreds to thousands of tiny coral creatures called polyps.
What organism lives inside coral?
zooxanthellaeBut tropical reef-building corals have tiny plant-like organisms living in their tissue. The corals couldn’t survive without these microscopic algae–called zooxanthellae (zo-zan-THELL-ee). This cutaway diagram of a coral polyp shows where the photosynthetic algae, or zooxanthellae, live—inside the polyp’s tissue.
What happens when coral polyps die?
