How have rising ocean temperatures affected coral communities?

A. Corals become less photosynthetic as the surrounding temperature increases.

B. Corals find fewer food sources when algal blooms increase due to warmer waters.

C. Corals attract fewer algal species when they become warmer.

D.Corals become bleached as they expel algae with increased temperatures.

As ocean temperatures rise, it can stress coral polyps, that causes them to lose algae. As a result, there is "coral bleaching". It is called that because the algae gives coral its color. When all the algae is gone, the coral is white.

The bleaching of corals in the world, are due to the increase in sea temperatures, but to understand how this changes corals, we need to know that.....

Coral bleaching

Coral bleaching is a serious ecological problem mainly related to the increase in ocean water temperature. This problem can occur transiently or fatally, killing the coral. In the bleaching phenomenon, the corals become translucent, making it possible to verify the calcium carbonate skeleton of these animals. This happens because of the expulsion of zooxanthellae algae or because of the loss of pigment from these algae, which live in a mutualistic association with the coral.

Question answer

D.Corals become bleached as they expel algae with increased temperatures.

with this information, we came to the conclusion that with the increase in sea water temperature, algae that are associated with corals are expelled.
