Question

1. what organisms do corals have a symbiotic relationship to and how? (3pts)

Explanation:

Corals have a symbiotic relationship with zooxanthellae (a type of algae). Zooxanthellae live within coral tissues. Through photosynthesis, zooxanthellae produce oxygen and organic compounds (like glucose) that corals use for energy. In return, corals provide zooxanthellae with a protected environment and nutrients (such as carbon dioxide and nitrogenous waste) needed for photosynthesis.

Answer:

Corals have a symbiotic relationship with zooxanthellae. Zooxanthellae produce oxygen and organic compounds for corals via photosynthesis. Corals offer a protected space and nutrients (carbon dioxide, nitrogenous waste) to zooxanthellae.
