Any animal need oxygen for respiration.
As there is oxygen in water (H2o o=oxygen) , if there is water there is oxygen, so yes.
plants
Definitely not. The fish in the sea take in the dissolved oxygen in the sea thru their gills.
At the summit of Mount Everest there is approximately only 33% of the oxygen that is available at sea level.The higher you climb any mountain the less oxygen there is to breathe. This is why climbers carry oxygen cylinders on there backs to help them breathe more easliy.The proportion of Oxygen to other elements is actually very similar to sea level, but the total amount of air or atmosphere is only about one-third that of sea-level, so there is about one-third as much oxygen as there is at sea level.
well.logically it just makes sense that since there is less oxygen above sea level (mt Everest roughly 1/3 of the oxygen at sea level) that there would be more oxygen below sea level. note: this is completely hypothetical and has no scientific backing whatsoever
because oxygen has been around for as long as there was sea life and when the first one came out of the sea they technically discovered oxygen
Oxygen is more soluble in fresh water than it is in sea water, therefore there is more dissolved oxygen in river water than sea water.
Underwater, animals have special adaptations to extract oxygen from sea water. Fish, for example, use their gills to convert water into usable oxygen.
they can stand so long without water and multiple stacked condition for a day. so a fewer oxygen is needed than any other aquatic organism.
Sea level oxygen is around 21% and Denver has about 18% available oxygen.
