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.
What else can I help you with?
Does coral breath?
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" .
Why soft corals live in deeper water than hard corals?
soft corals live deeper water than hard corals because soft corals do not create a hard outer skeleton as the hard corals do.
Are corals decomposers?
Corals are not decomposers. They are consumers.
Are corals plants or fish?
Corals are plants.
Differences between hermatypic and ahermatypic corals?
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.
Can sea corals be eaten by humans?
No, corals are not edible.
Do corals have exoskeleton?
Yes, corals are composed of an exoskeleton
What is the effect of dynamite fishing and muro ami on the productivity of corals?
dynamite fishing and muro ami can destroy corals so if there are less corals, less corals will be produced.
Does corals eat zooxanthellae?
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.
How does algae benefit the corals?
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.
What has the author John West Wells written?
John West Wells has written: 'Eocene corals from Eua, Tonga' -- subject(s): Fossil Corals, Fossil Fishes, Fossil Otoliths, Paleontology 'Some fossil corals from the West Indies' -- subject(s): Fossil Corals, Paleontology 'Fossil corals from Eniwetok Atoll' -- subject(s): Fossil Corals, Paleontology 'Recent corals of the Marshall Islands' -- subject(s): Corals
Difference between cnidarians and corals?
There is none. Corals are cnidarians.
