Corals are in danger because people are breaking them and taking them for souvenirs.
soft corals live deeper water than hard corals because soft corals do not create a hard outer skeleton as the hard corals do.
Corals are plants.
Corals are not decomposers. They are consumers.
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.
No, corals are not edible.
Yes, corals are composed of an exoskeleton
dynamite fishing and muro ami can destroy corals so if there are less corals, less corals will be produced.
Water pollution in the ocean is creating havoc for marine life. The Great Barrier Reef being made up of corals is being adversely affected for growth of corals. This will disturb the whole ecosystem around the reef in particular and in the ocean in general.
No corals doesn't eat zooxanthellae they only eat zooplankton. Zooxanthallae helps corals to live and keeps corals colourful.They live on the coral polyps.
Many corals, specifically hermatypic corals, contain symbiotic algae that provide the coral with sugar from photosynthesis. Algae also feed zooplankton, which corals feed on. Basically, algae provide corals with food, indirectly.

Corals do not give birth.
