Hello my name is Rachel Baker. In my Science class we are learning about the ocean. It will be a very big help to my project. I can offer instead some of the most important aspects of the Great Barrier Reef, points that you should research further and include in your report. There are ample resources, I am sure, that can help you learn about each of these important aspects.
Diversity refers to the amount of different types of life found in an area.
I can tell you that the organisms that supply the backbone of a reef is coral, a special type of coral that secretes calcium carbonate for its own shell while it is alive. Then, when it dies, the skeleton is left behind, and other animals move in to live on that hard shell. Good luck on your report. Write back if you have any more questions.
