Much less than the approximate 21% in the air. Perhaps half that. Fish need a large energy expenditure to strain oxygen from the water. Most of the oxygen produced by phytoplankton, for instance, is vented into the atmosphere.

What is the oxygen percentage at sea level?
the aircontains 20.93% oxygen-whether you are swimming in the Dead Sea in Israel (1,369 feet or 417 meters below sea level) or standing on top of Mount Everest in Nepal (29,035 feet or 8,850 meters above sea level). the barometric pressure is lower the higher in altitude you go so the pressure of oxygen is lower therefore its harder for your lungs to absorb the oxygen.
What is the average oxygen level in air at sea level?
21%
What's the percentage of oxygen in air at sea level to 4 decimal places?
2.66666666667 is the decimal of oxygen in the air
Its composition is 78 percent nitrogen 21 percent oxygen and 1 percent other?
The earth's atmosphere at sea level.
How much oxygen is in 1 liter of air?
Approx 180ml
Why is there no oxygen on mt Everest?
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.
How much oxygen in air?
Oxygen is it's own element. Air is a combination of elements. That question is not even a sentence, but I think your answer is Air is 19% Oxygen at sea level.
Oxygen levels in the sea decrease with depth. how do deep sea divers get there oxygen?
plants
How much O2 on Everest summit compared to sea level?
At the summit of Mount Everest there is approximately 33% of the oxygen that is available at sea level.
How much oxygen is available 5.5 kilometers above sea level?
From sea level to an altitude of 300 meters there is enough oxygen. After 300 meters of altitude, there is enough oxygen. 4500 meters to 4800 meters of altitude and low atmospheric pressure due to lack of oxygen to human breath.
Is there any oxygen in the sea?
no
How much oxygen does a submarine have?
Modern nuclear submarines make their own oxygen as needed by electrolyzing sea water. The amount of oxygen carried by conventional submarines depends on the design and size of the particular submarine.
Why is it hard to breath on the top of a mountain?
Answer: Because the percentage of oxygen in the air is not as much as it is at sea level. When higher altitude is attained, oxygen levels drop. Hope this helps.
Does dissloves oxygen in water harmful?
Definitely not. The fish in the sea take in the dissolved oxygen in the sea thru their gills.
Is oxygen a gas dissolved in sea water?
Oxygen does dissolve into sea water, as do many other gasses such as CO2.
Why is there uncertainty about who really discovered oxygen?
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
More oxygen sea water than river water?
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.
