Which of the following statements is false regarding water intake and output by the body?
an increase in the amount of beverages taken by mouth would increase the urine output.
an increase in fluid taken by mouth would reduce the amount produced by metabolism.
an irritation to the colon that leads to diarrhea would increase the proportion of water lost through feces.
the proportion of fluid lost by the body as sweat would increase during exercise.

The correct option is this: AN INCREASE IN FLUID TAKEN BY MOUTH WOULD REDUCE THE AMOUNT PRODUCED BY METABOLISM.

Explanation:

Generally, the amount of water consumed by a person normally leads to increase in the amount of urine that the person will excrete, that is, the higher the quantity of water consumed, the higher the quantity of the urine that will be excreted under normal circumstances. Thus, the statement given in option B is false. The statements given in Option C and D are right; during exercise the quantity of sweat produce and lost by the body is higher than the one that is produced when one is not exercising. Also, diarrhea usually lead to loss of water from the body.  

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
