Answer 1

Coral and algae live together in a type of relationship called symbiosis. In this type of relationship, both organisms will benefit. In this case, the algae perform photosynthesis, producing oxygen and organic compounds that provide energy for the coral, and the coral provides a protected environment and the nutrients necessary for the algae's growth. Because the two organisms depend on each other for survival, they could both suffer significantly or even die if the algae are ejected from the coral.
