Air.
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.
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.
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.
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.
Salt water is a mixture of water and salt, oxygen is a compound, and air is a mixture of gases like nitrogen, oxygen, and carbon dioxide. Oxygen is an element found in the air, but salt water does not contain oxygen as an element.
It has dissolved oxygen.
Oxygen in water and oxygen in the air have different levels of availability for organisms to use. Oxygen in water is more readily available to aquatic organisms since it dissolves in water more easily. However, terrestrial organisms, like humans, primarily rely on oxygen in the air for respiration.
oxygen, and water can be found in the air
Air has more oxygen compared to an equal volume of water. Air is composed of approximately 21% oxygen, while water contains dissolved oxygen, but in much lower concentrations, usually around 5-8 parts per million.
Tadpoles get oxygen from water like fish do.
