The amount of water a body requires for survival is dependent upon the climate and the individual’s level of physical activity. select the best answer from the choices provided t f

True,  

The amount of water required to support healthy living and life is dependent on both the climate and the amount of physical activity of an individual.  

People living in extreme cold climate may not require as much water as required by people living in extreme hot climatic conditions. During hot climatic conditions, the loss of water from our body increases on account of excessive sweating and thus the water requirement increases. The same is the case with individual doing high physical activities which accounts to increased sweating, along with high rate of breathing which require more cellular respiration and fluid consumption to compensate the loss of fluid and energy in the body.  

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
