 That's absolutely correct. And by definition, bleaching is the loss of those algae. So when the water temperature exceeds some threshold, for somewhat unknown reasons, actually, this is an open question, the coral expels those obligate symbionts. And so essentially it goes into a point where it's at risk. So if it doesn't have the symbionts, which provide it with most of the energy it needs to grow, the coral essentially begins to starve.
