When coral is bleached, it typically loses the symbiotic algae known as zooxanthellae, which live within its tissues. This process leads to several consequences. Among the options provided:
D) Da coral releases algae into da ocean is the most accurate.
Bleaching occurs when stress factors like increased water temperature or pollution cause coral to expel the zooxanthellae, resulting in the coral turning white (bleached). If the coral does not recover and the stressors persist, it can lead to starvation and ultimately death, but this process does not happen immediately.
So, while options A and B have some truth in terms of the potential consequences of prolonged bleaching, option D most closely describes the immediate action that occurs during bleaching.
