Question

Quizplus · Accepted Answer

Zooxanthellae are symbiotic algae that live within the tissues of corals and other marine organisms. They play a crucial role in coral reef ecosystems by recycling phosphorus and nitrogenous waste compounds, which are byproducts of the host's metabolism. This symbiotic relationship is beneficial for both the host and the zooxanthellae, as the algae receive protection and access to sunlight, while the host gets essential nutrients recycled by the algae.
