Coral Bleaching

Coral bleaching occurs when the water gets warmer and coral expels the zooxanthellae living in its tissues, causing it to turn white. after the coral bleaches, coral animals are replaced by algae, which serve as a short-term replacement for food. However, after an extended period of time, the basis of the food chains ends up being lost.

Coral bleaching is an issue because coral reefs provide food and shelter for many marine organisms. When the coral dies, so do he animals that depend on it.
