Why is it important that living organisms not reach equilibrium in the concentrations of oxygen and carbon dioxide?
Mashcka [7]

Answer:

The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop.

Explanation:

  • Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
  • If living  organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
  • This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
  • If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.
