The Awareness Quiz On Coral Bleaching

Coral Bleaching takes place when coral polyps expel algae that live inside their tissues. These algae are responsible for the color of the coral reefs. This is caused by above-average sea water temperatures and global warming. Normally coral polyps live in an endosymbiotic relationship with these algae and they are crucial for the health of coral and the reef. How much do you know about this grave problem? Find Out!
