Source sentences:
text: Zooxanthellae is a type of algae that produces oxygen by photosynthesis and provide glucose, glycerol, and amino acids to the coral polyps.
text: With less available light, less photosynthesis occurs, and thus zooxanthellae produce less oxygen.
text: Therefore, in order to help zooxanthellae produce as much oxygen as possible, Elkhorn coral live in shallow regions between 1 and 5 meters to ensure that abundant light reaches the zooxanthellae, maximizing photosynthesis.
