Coral reefs support marine biodiversity by providing a habitat for a wide variety of marine organisms such as fish, invertebrates, and algae. The complex structure of coral reefs offers shelter, food sources, and breeding grounds for many species, contributing to the overall ecosystem's diversity and productivity.
Additionally, coral reefs protect coastal areas by acting as natural barriers against waves, storms, and erosion. The physical structure of coral reefs helps dissipate wave energy, reducing the impact of coastal hazards such as flooding and erosion. This protection benefits not only the marine life within the reef ecosystem but also the adjacent coastal communities by maintaining shorelines and supporting local economies dependent on tourism and fisheries.
