PPT-Introduction to Coral Reef Ecosystems

Reef Development Coralline algae precipitate calcium carbonate Sponges secrete silica Dominant species Framework Builders because they provide the matrix for the growing reef Reef Development. Built entirely by biological activity. CaCO. 3. solubility low above 20. o. isotherm. Radioactively labeled Ca absorption low on cloudy days. Global distribution limited by temperature. 70 m is max depth (1-2% surface illumination). By Harsha Lakamsani. Introduction. Coral Reefs are made of limestone structures of dead and living stony coral. Coral polyps are formed by red and green coralline algae. Coral gets color from . zooxanthellae.
