Why is coral bleaching a major concern for ecologists?
A Coral provides food and shelter to a wide variety of ma- rine life. When coral bleaches, the coral reef ecosystem can no longer sustain high levels of biodiversity.
B Coral bleaching can lead to eutrophication, a process where decomposition of organic matter leads to areas of water with low concentrations of oxygen.
CWhen corals bleach, they release toxins into the ocean that can kill other marine life.
D When bleached coral is ingested by primary consumers, they can become poisoned.
