Zooxanthellae are protists that live inside reef-building coral polyps and provide the corals nutrients. Corals protect zooxanthellae and give then access to light for photosynthesis. When most of the zooxanthellae inside corals die, the corals also die. Zooxanthellae living in closely related coral species may not be closely related, while zooxanthellae living in distantly related corals may be more closely related. Which description of the relationship between zooxanthellae and corals is accurate?

It is a symbiotic relationship that most likely evolved on coral reefs in a number of geographic locations

What is the organelle found in the animal cell that breaks down old organelles and digest ( breaks down ) nutrients

Lysosomes
