they breathe water
Via the gills, by osmosis. The oxygen they need is dissolved in the water.
Fish extract the oxygen out of the water using their gills, thus leaving the water hydrogenated, which some plants and animals (marine ones) need as opposed to oxygen so balance is restored. Hope this helps.
Fish breathe underwater using their gills.
Fish "breathe" by gulping down water. This water passes over the fishes' gills, made up of the same flesh as our lungs (roughly), which extract the water using either active transport, or simply a concentration gradient on a partially permeable membrane, I'm not quite sure. Either way, the oxygen is extracted from the water, and Carbon Dioxide replaced. The water then passes out the slits in the side of the fishes head.
This method is very effective, meaning the fish can extract around 80% of the oxygen in water, which is EXTREMELY important, as water only contains 2-5% oxygen, as opposed to 20-something% for air.
Also, the ease of which the oxygen is extracted depends on the water temperature, whether it is salty, and other factors. This is why most Freshwater Fish can't survive in the ocean.
No, the fishes breathe through their gills.
Fish breathe underwater using their gills. As water passes over their gills, oxygen is absorbed from the water and carbon dioxide is released. This process allows fish to extract oxygen from the water and breathe efficiently.
Fish breathe through their gills. There are usually gills on either side of the pharynx. Gills have thread-like structures (filaments). These filaments exchange the oxygen and carbon dioxide.
Fish breathe oxygen, which they extract from the water with their gills.
A fish breaths through it's gills.
yes, fish can breathe. they do this by using their gills.
Most fish breathe with gills.
fish breathe through their gills
Yes, fish do 'breathe' through gills.
Fish breathe with the help with gills.
Most fish breathe through their gills, not moist skin! :)
Jawless fish breathe from gills.
through gills
No,not all fish breathe through gills
thay can breathe by using their gills
They do breathe air.
Whales breathe with lungs, and fish use gills.
