27 multiple answer 1 point multi - select: what causes coral bleaching ocean acidification coral turns white in the dark keeping oceans healthy rising ocean temperatures

Explanation:

Coral bleaching occurs when corals expel the symbiotic algae (zooxanthellae) living in their tissues, turning white. Ocean acidification, caused by increased carbon - dioxide absorption by the ocean, and rising ocean temperatures stress corals and lead to bleaching. Keeping oceans healthy does not cause bleaching, and corals do not turn white in the dark as a cause of bleaching.

Answer:

A. Ocean Acidification
D. Rising ocean temperatures
