No, not at all. Most fish extract the oxygen that is dissolved in the water, not the oxygen that is bound to hydrogen in the formation of water.
This is one reason that most aquariums have an aerator bubbling away - it is adding oxygen to be dissolved by the water.
Go look at some other website!
They sure do.
Yes,of course they do!
yes,all plants give out oxygen.
If you want less oxygen breathe it in from the water or get a fish to do it
They breathe in the chemical water to get oxygen.
For alge eating fish, food. But if you are a normal fish the alge take the oxygen out of the water and fish need oxygen to survive so not very good things for normal fish.
The metabolism of an organism, whether land based or aquatic, generates useful chemical energy through the oxidation of chemicals such as carbohydrates. This requires oxygen. Land based animals acquire oxygen from the air; fish acquire oxygen from the water. In order for them to be able to do this, they need to have oxygen dissolved in the water. In water that has no dissolved oxygen, fish suffocate.
No. Cola is full of CO2. Fish need to extract oxygen from the water using their gills. There are not enough free oxygen atoms in cola.
Water weed takes in the carbon dioxide released by the fish and turns it into oxygen in a process called respiration. The fish in turn breathe in the oxygen and release carbon dioxide, starting the cycle again.
Tadpoles get oxygen from water like fish do.
Fish can absorb water by the gills
High nitrate levels in the water cause an increase in algal growth with reduces the amount of oxygen in the water, which in turn cause the fish to die.
Fish breathe oxygen, which they extract from the water with their gills.
Fish get oxygen from the water using their gills
Fish have gills, which allow them to take oxygen out of the water, just as we take oxygen out of the air, to put it simply.
Oxygen
Oxygen
Of course all fish need oxygen even puffer fish....
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
They need water Fish can not process oxygen the same way mammels do. They get their oxygen throu molecules in the water.
