I will refer to delivery and removal of CO2 and O2 as "gas exchange," which is the sum of the rate of diffusion into and out of an organism. The total amount of gas exchange is dependent on the rates of diffusion and the rates of diffusion are dependent on the availability of moisture, surface area and concentration gradients. When we are dealing with corals there is no need to pay attention to the availability of moisture because they grow in water, since they breathe the same way that fish do, and therefore moisture is not a limiting factor for diffusion. Surface area is controlled mostly by the corals themselves; in the short term corals can change their polyp extension and colony expansion, and in the long term corals can modify their morphology. The only factor left for aquarists to control is the concentration gradient, which is affected by the degree and type of water motion.
they have a mouth in the centre which they breath from probably from the air that reaches the water because they do live in very shallow waters so they get enough air to breath
Coral have a mouth, and their breathing process includes something called gas exchange. There breathing process is that of a fish only without gills.
Not in the way you are probably thinking of breathing. They undergo photosynthesis, as they are plants, which means they absorb CO2. This is plants version of "breathing" .
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.
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.
