This area supports more than 7,000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals. Reset Help molecule, a DNA double helix organ . Polyps are capable of drawing dissolved calcium from seawater, and solidifying it into a hard mineral (calcium carbonate) structure that serves as their skeletal support. a very specific natural environment made up . Because photosynthesis requires sunlight, most reef-building corals live in clear, shallow waters that are penetrated by sunlight. This global profile provides an overview of why coral reefs are important, what threats they are facing, what makes them resilient and what we can do to save them. A .gov Parrotfish actually eat the reef itself. Individuals make up a population; populations make up a species; multiple species and their interactions make up a community; and multiple species and their interactions make up ecosystems when you include the abiotic factors.
