A reef is primarily created through the accumulation of calcium carbonate produced by coral polyps, small marine animals that build their hard exoskeletons. As these polyps grow and reproduce, they form large colonies that contribute to the structure of the reef. Over time, additional organisms like algae and mollusks also contribute to the reef's development by adding more calcium carbonate. Environmental factors such as water temperature, salinity, and light availability play essential roles in the growth and sustainability of the reef ecosystem.
