by growing gills
Lungs. (or gills for fish).
With the exception of nuclear fusion oxygen cannot be obtained by heating anything. Certainly no heating process on earth is capable of producing oxygen.
Oxygen is soluble in water (dissolves in water). This is the basis for marine animals who breathe through gills and similar structures to get their oxygen.
Oxygen is found as a free molecule in the air and as a component of many organic and inorganic compounds in the earth's crust. For commercial purposes, it is usually obtained by using extreme cold to condense it from the atmosphere.
All fish breath through their gills, there is oxygen in water, as such, they take the oxygen through their gills.
The fishes gills are like filters. when water goes in a fish's mouth, it goes through the gills, which filter out the oxygen.
Oysters have gills. They absorb oxygen from the water.
like any other fish. water passes through their gills and the gills absorb the oxygen through their gills.
They get oxygen from their gills.
Yes, seahorses have gills. They have gills to get oxygen from the water so they can breathe.
they have gills
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
Sharks have gills so they can breathe. They absorb the oxygen out of the water using their gills.
To exchange for oxygen in water.
they dont. Oxygen in the water through there gills
Land mammals do not have gills because there is no water needed to filter out to get oxygen. Fish have gills because they need to filter out water (and other objects) to get the oxygen to breathe.
