it uses its gills
During cellular respiration, glucose gets oxidized to form carbon dioxide and water, while oxygen gets reduced to form water. Glucose loses electrons and hydrogen atoms, which are transferred to oxygen during the process, resulting in the reduction of oxygen to water.
Of course all fish need oxygen even puffer fish....
Because the warmer the water gets the less oxygen the water contains.
respiration is breathing so when the oxygen gets to our lungs it gets distributed through the body
Oxygen that is dissolved in the water crossed ghe gill menbrane by diffusion. The oxygen is dissolved in the water like carbon dioxide in a beer. This oxygen is not a part of the water molecule. The oxygen in the water molecule is not available to the fish, when dosolved oxygen gets low, yhou have a fish kill.
Water has oxygen dissolved in it. It gets this oxygen from plants, agitation, air stones, air to surface transfer, etc.. Fish require oxygen to live. If there was actually no oxygen in the water, the fish would suffocate in minutes. Otherwise it would depend on the amount of water, the number of fish, and many other factors.
Breath! All living things need oxygen to live (except plants). oxygen gets trapped in the water and the fish use it to breath.
Water gets its oxygen (which the fish need to absorb through their gills to ''breathe'') by absorbing it from the air. If the water surface is not in contact with air, the fish will quickly use up all the oxygen in the water and die.
The fish gets its oxygen from the water, from the limited amount dissolved there. Unless more oxygen is added to the water, the fish will "drown" (asphyxiate). In goldfish bowls, it is important to trickle in some water regularly to encourage oxygen intake while also balancing evaporation. In larger aquariums, or with more fish, an aerator bubbles air through the water to add oxygen.
Most animals breathe the same way humans do, with lungs. Fish use gills, which strip oxygen from water and lets the water pass through them. Plants obtain energy via a process called photosynthesis. The plant gets energy from sunlight, water and carbon dioxide and expels oxygen, which we breathe.
Because it doesn't enter their lungs,it gets converted into oxygen through the gills.
Fish have gills- thy are similar to lungs, but water gets pumped through them. Oxygen dissolved in the water transfers (in the gills) to the bloodstream of the fish, and carbon dioxide gets flushed out.
