There are many reasons of this problem but the most important is the hydrostatic pressure.
Hydrostatic pressure can be described as the pressure or weight exerted by the water on the object.
With every increase in 10 meters the pressure increase by 6.47kg (14.27lbs) each square inch of surface.
Due to extreme pressure, oxygen level in the cells of body fluctuates and person becomes unstable and can become unconscious.
Answer:
Respiration is a process in which carbon is released in the atmosphere in the form of carbondioxide.
Explanation:
Respiration is energy generating process. In this process, food substance which contains glucose molecule is broken down in the mitochondria of the cell which releases carbondioxide, water and energy in the form of Adenine tri phosphate (ATP). Energy is used by the cell in different processes and activities while Carbondioxode gas is released in the atmosphere.
