The lungs remove oxygen from the air.
By bubbling oxygen (or air) through the water, splashing water through the air (waterfall). That is where the oxygen that fish breathe comes from. It is separate from the oxygen that was chemically combined with hydrogen to form the water.
It is. Dry air lacks water vapor, not oxygen.
They get oxygen from the water and air depending on what species of crab they are
it comes from the air around you
Air conditionning has no chemical reactions that would lower oxygen levels. It does however reduce the humidity in the conditionned air. This would remove moles of water from the air and increase the perecntage, but not the mass, of the oxygen in an air sample.
The lungs remove oxygen from the air.
Dolphins actually have to surface to get oxygen from the air. Tuna and squid have special lungs called "gills" that allow them to remove oxygen directly from water.
One way is by breathing. Another way is by burning something
What we breathe is air, and oxygen is just 20% of the air. Oxygen does not contain water, it is an element and it contains only itself. However, air does contain some water vapor.
Air.

No. Turtles get oxygen from air.

They breathe through breathing tubes that will stick out of the water to get oxygen from the air.
The two main sources for obtaining oxygen are the air - 23% of air is oxygen - and water by electrolysis.
Oxygen is latent in the water, because the water absorbs gasses in the air, like how water absorbs sugar. Since the air (and so oxygen) is in the water, the oyster can use it.
