The amount of atmospheric
Viktor [21]

Answer:

The amount of atmospheric oxygen is more than the amount of dissolved atmospheric oxygen in water.

Explanation:

The oxygen which is present in the atmosphere is much higher than the oxygen which is present inside the water. About 21 percent of oxygen is present in the atmosphere while only 1 percent of atmospheric oxygen is dissolved in the water. Oxygen is higher in atmosphere because this oxygen is used during respiration of organisms. If concentration of dissolved oxygen is very high, the marine animals die.
