Description:Coral reefs are diverse and critically important marine ecosystems. When corals are stressed they expel the symbiotic algae living in their tissues, causing them to become completely white, or “bleached”. Researchers use the sea anemone Aiptasia as a model organism to study coral reef bleaching. Like coral reef polyps, Aiptasia partners in symbiosis with algae to help each other make energy and survive through the cellular processes of photosynthesis and cellular respiration. In this lesson, students explore data to determine how growth rates for Aiptasia with symbiotic algae differs from Aiptasia that do not have algae. Students use the trends they see in the data to explain the cycling of matter and flow of energy in the model organism, and then apply this knowledge to their understanding of coral bleaching.
