The amount of water a body requires for survival is dependent upon the climate and the individual’s level of physical activity.
Zigmanuir [339]

Answer:

False

Explanation:

Water is essential for our survival, without it there is literally no life. In addition, if we do not drink the right amount of water, we can present serious problems that will be extremely harmful to our health.

The amount of water necessary for survival is variable for each organism, because it depends on some factors such as: the person's age, weight, height, the physical activity they perform and the climate and temperature of the environment where they live.

It is important to emphasize this, because many claim that drinking 2 liters of water a day is sufficient for all individuals in the world, but this is not correct to say, because it is necessary to take into account all the factors mentioned above, before determining the adequate amount of water.
