Definitely not. The fish in the sea take in the dissolved oxygen in the sea thru their gills.
Physical weathering is a type of weathering in which minerals react with dissolved oxygen in water. This causes chemical changes to take place in the minerals.
Water can be depleted of it's oxygen by a number of different ways. Short of putting the water in a vacuum and "sucking" the dissolved oxygen out, oxygen-breathing organisms such as fish take oxygen from the water through respiration, for example. It is unlikely a large body of water to become completely deoxygenated due to the presence of photosynthetic aquatic organisms (plants) and the fact that oxygen is also dissolved in the water at the water's surface.
A trout intakes the dissolved oxygen in the water through it's gills - just like any other fish.
No, but they have gill chambers which they use to store water, to take in dissolved oxygen.
Water scorpions have air tubes that stick out of the water surface to take in atmospheric oxygen. They come up to the surface several like Dolphins and Whales.
well oxygen dissolves in the water and makes it dissolved oxygen and so they still take in regular oxygen just mixed with water
yes. fishes receive oxygen under ocean . This is because of aquatic plants.
They breathe by the constant flow of water through their bodies by way of bodily pours and they take up the dissolved oxygen, just like fish do with their gills.
Yes, provided there is oxygen dissolved, which will be the case if the distilled water is open to the air, a rusting reaction will take place. It will be slow. The reaction is much quicker when there are dissolved salts.
Yes organisms take oxygen from the air and aquatic organisms take oxygen from the water using their gills. Some do. Most only from one or the other. For example a tuna fish gets pretty much all its oxygen from oxygen dissolved in water. Humans get all our oxygen from the air. Mudskippers get oxygen from both. Yes. Land animals take in oxygen that plants release using their noses. On the other hand, aquatic or marine animals take in oxygen using their gills.
If both t etap water and the distilled water are open to the air and both have dissolved oxygen then the iron nail will rust faster in tap water. Rusting requires dissolved oxygen and goes faster if there are dissolved salts.
