Carbonate environments

Conditions• Photosynthetics organisms typically flourish in theupper 10-15m of the sea, most calcareous organismsare found here.• Hermaltypic corals are dependent on symbioticalgae. They like clear water (nutrient starved- toomany nutrients and the water gets clouded withalgae), with little to no sediment input. They preferstrong currents.• On the other hand, most other benthic marineorganisms prefer quiet waters.
