coral Reef Health


Through this class we will learn to describe how environmental change affects the ecosystem of a coral reef and explain what coral bleaching is.

We may then practice our language skills by reading an article, participating in a class presentation, and writing down an explanation of coral bleaching.


Please write down an example of energy transfer 


Examples of energy transfer in biology:

Food web or trophic levels, sound waves, electrical currents in electric eels, photosynthesis,

WHat is coral bleaching?



Bleaching
 occurs when warm ocean water stresses corals to the point that they expel the tiny algae, known as zooxanthellae, that normally live inside their tissues. The algae provide the corals with most of their food, as well as their color. If the heat stress is lessened soon enough, the coral can recover.
