Question

Quizplus · Accepted Answer

Increases in sedimentation, sea surface temperatures, and pollution can lead to stress on the coral, causing it to eject the algae living within it. This is known as coral bleaching and can have detrimental effects on the health and survival of the coral. Age of the polyp and solar activity do not have a direct impact on the ejection of algae from coral, and sea level rise may affect coral in other ways but is not directly related to algae ejection.
