Oxygen that is dissolved in the water crossed ghe gill menbrane by diffusion. The oxygen is dissolved in the water like carbon dioxide in a beer. This oxygen is not a part of the water molecule. The oxygen in the water molecule is not available to the fish, when dosolved oxygen gets low, yhou have a fish kill.

How do you separate Hydrogen and Oxygen gases in industrial electrolysis of water process?
In electrolysis, oxygen and hydrogen gas are produced at different electrodes (oxygen at the anode and hydrogen at the cathode). Since these electrodes do not have to be in close proximity, the hydrogen and oxygen will bubble upwards into separate collection vessels. If you needed to separate hydrogen and oxygen once mixed, the easiest way I can think of would be to cool the mixture to ~60K. At this point the oxygen would condense and leave hydrogen gas.
Why do fish use 15 percent of their energy to move water over its gills?
To breath by extracting oxygen from the water.
How much oxygen is in the sea?
Much less than the approximate 21% in the air. Perhaps half that. Fish need a large energy expenditure to strain oxygen from the water. Most of the oxygen produced by phytoplankton, for instance, is vented into the atmosphere.
Can you list out topics for paper presentation on renewable energy?
solar energy is one of the best renewable energy resources and new mechanism to efficiently convert the solar energy to mechanical energy are being developed. Lot of R&D is going on in to this topic in the labs of MIT. It deals with breaking water into hydrogen and oxygen. you can follow it up from this link. http://web.mit.edu/newsoffice/2008/oxygen-0731.html
How many liters of water are needed to react with 2L of oxygen to make water?
Water does not need to react with oxygen to make water!
Fish can extract oxygen from water using what?
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
Would it be easier to separate the sugar from the water or to split water into hydrogen and oxygen?
it is easy to separate sugar from water. allow the water to evaporate to get back sugar. splitting of water into hydrogen and oxygen requires more energy than the above.
How does the thickness of lamellae affect the oxygen uptake by a fish's gills?
Osmoregulation is the maintenance of constant pressure of osmosis in the fluids of an organism. This helps the flow of water through the gills to keep entering the cells, rather than pulling out the water, which helps to bring in the needed oxygen.
What is produced when a compound is heated?
Your question is invalid, your question should be What is separated when a compound is heated, because heating a substance is basically adding energy to it. and the energy is likely to separate compounds. For example when you add electricity(energy) to water it will separate water into oxygen and hydrogen. It will also apply for heat energy, If you add enough heat to separate the bond of water.
How do fish get oxygen from under water?
Fish gills contain rows upon rows of lamellae, which are thin, disc-like membranes loaded with a capillary network. The water flows across the lamellae, and oxygen and carbon dioxide are exchanged directly across the capillary membrane. Humans have similar capillary interchange sites in the lungs, and the gas exchange occurs in much the same fashion, only the fluid from which we get our oxygen is air, whereas fish get their (dissolved) oxygen from the water.
What kind of energy is used when water decomposes?
To separate water into hydrogen and oxygen, electrolysis is usually used; this uses electrical energy. Of course, the electrical energy can be generated in any of several ways.
What do the alveoli of the lungs the microvilli and villi in the intestine and the gill lamellae in fishes gills have in common?
The microvilli and villi in the intestine increase the absorbent surface where nutrients are transported into the blood. The alveoli in the lungs and gill lamellae bring oxygen in the air and water to the bloodstream,
What is used to separate hydrogen and oxygen?
Electrolysis, the passing of electric current through water will separate the water into oxygen and hydrogen molecules.
Does oxygen and nitrogen contain water?
No; oxygen, nitrogen, and water are all separate elements.
How do you separate hydrogen and oxygen gases without explosion in industrial electrolysis of water?
you do this and that and this and also that you do this and that and this and also thatYou can separate water into oxygen and hydrogen by the process of electrolysis.
How does the electron chain transfer light energy in photosynthesis?
Light breaks down water into hydrogen and oxygen, the oxygen is then released. Next the hydrogen and its electron separate so that they are H+ and e-. The electrons are dragged across which creates massive energy.
Can water be used to separate hydrogen and oxygen?
yes
