Oxygen. Aquatic animals need it too. They just have to be a lot more efficient at getting it. Air is about 21% oxygen, that's 210,000 parts per million. In most natural water sources, dissolved oxygen is about 14 parts per million. But if it's not there - your fish die.

Describe how fish float in water?

Fish float in water due to their swim bladders, which are gas-filled organs that control their buoyancy. By adjusting the amount of gas inside the swim bladder, fish can control their depth in the water column and maintain their balance. Additionally, the shape and density of a fish's body also contribute to its ability to float and swim efficiently.


What do fish take out when they take in water?

When fish take in water, they extract dissolved oxygen through their gills, which is essential for their respiration. The gills filter out the oxygen from the water, allowing fish to breathe. Additionally, fish may also remove carbon dioxide and other waste products from their bloodstream as water passes over their gill filaments. Thus, the primary function of this process is to facilitate gas exchange for survival.


What gas do fish take in?

They take in oxygen with their gills.


Why should a fresh water fish be placed in a fresh water aquarium?

If you wish a fresh water fish to be kept alive and well so that it may be studied or kept as a pet. The fish will need to be placed in a suitable container with suitable water that has suitable parameters. Without water a fish will die just like you would die if your air supply was removed. If the fish was a fresh water fish and the water was salt as opposed to fresh, to the fish, it would be similar to what would happen to you if someone put poisoned gas in your personal air supply. You would be extremely ill and then die. So would the fish.


Where does the water come from from the air?

The gas that you see coming out of water when it is boiling is water vapour being produced because the temperature and pressure are right at a given point in time. Air in water such as the bubbles you see collect on objects submerged in water or the air that fish breathe is dissolved into the water at point of contact.


When fisherman catch fish with a spearthey aim at a point slightly below the spot where the fish seem to be. Give reason.?

To see the fish, light passes from air through the water. As light crosses over from the gas (air) to the liquid( (water) the density increases. The greater density bends (refracts) light, displacing the apparent location of the fish. You must aim at where the fish is, and not where its image is.
