8. Marine animals live in salt water, which is a hypertonic environment, there is more salt in the water than in the cells. To prevent losing too much water from their bodies, these animals’ intake large quantities of salt water and then secrete the excess salt. Why is the balance of water molecules inside and outside the cell is extremely important for the survival of all organisms, including humans? here is more salt in the water than in the cells. To prevent losing too much water from their bodies, these animals’ intake large quantities of salt water and then secrete the excess salt. Why is the balance of water molecules inside and outside the cell is extremely important for the survival of all organisms, including humans?

This balance is extremely important because all life is essentially based on balance or homeostasis. It depends on each organism on how much water they need, but they do need a specific amount of water in order to maintain homeostasis. An organism will function the best when they maintain homeostasis. Therefore, this balance allows an organism to function in a state of almost absolute equilibrium.
