How do coral reefs affect the carbon levels in the ocean?

• only release carbon as the algae do photosynthesis

• the algae absorb carbon through photosynthesis & release through respiration

• the coral remove some carbon to build their exoskeletons

• only release carbon as the algae do photosynthesis
