Identify what is released (products) during cellular respiration identify what is used (products) during cellular respiration identify the ending compounds during cellular respiration identify the role of glucose in cellular respiration identify where cellular respiration occurs in the cell

the answer is a. hope this .

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
