Be sure to close the extra window by using the X in IBM, or the close box in MAC when you are finished using them.

  Introduction


Now we will examine the biology of coral reefs. Coral reefs are ecologically complex. The organisms that live in them interact with each other in a variety of ways creating a rich web of life. Each reef species has unique characteristics that allow it to specialize on particular reef resources in ways that other species cannot. In this lab activity you will study the basic characteristics of reefs, thier structure, and how they have come to be.
