Corals are not decomposers. They are consumers.
Corals are plants.
Coral reefs are a group of cnidarians that provide food and shelter for many marine animals. They create complex ecosystems that support a diverse range of species through their calcium carbonate structures.
Hermatypic corals contain zooxanthellae (a symbiotic algae), whereas ahermatypic corals do not. It is like saying that hermatypic corals are photosynthetic, where ahermatypic corals are non photosynthetic.
Coral reefs provide habitat, food, and shelter for a wide variety of marine species. Corals play a key role in the ecosystem by creating complex structures that support biodiversity. They also contribute to carbon and nutrient cycling in reef ecosystems.
