Australia is home to one of the world's largest, most complex and amazing ecosystems: the Great Barrier Reef. This video explores the reef's biotic and abiotic features, including coral formation and how changes in abiotic factors affect it; the food chain, nutrient cycle, and carbon cycle; and the impact of human activity. It is an excellent resource for middle/senior students of geography, biology, and environmental science.
