Description

This resource explores Australia’s Great Barrier Reef, the largest structure on Earth built by living organisms. Consisting of almost 3000 individual reefs, the Great Barrier Reef houses an incredible array of biodiversity. This resource demonstrates the types of relationships among living things that have contributed to this incredible biodiversity and elaborates on some of the adaptations that have enabled species to survive and reproduce in this unique habitat.

This resource has a great deal of information. Younger students might need some instruction and practice in moving the cursor around the screen and taking advantage of all of the features. For example, if students are interested in a particular species displayed on the screen, they must select a relationship type that applies to that species or the information will not be available.
