Explain why water moves into Respirometer's pippettes? - explain why water moved into the respirometer pipettes

I assume you speak very simple respirometer normally processed in a glass bottle and a single hole rubber inserted with a pipette and the tip of the pipette into contact with water. The inside of the bottle, put an animal of a kind and a container or a bag of potassium hydroxide (KOH). As the animal breathes, consumes oxygen (O2) and carbon dioxide is produced (CO2). Collected KOH K2CO3 CO2 form, a solid, not gas. Thus, as O2 is used, the amount of gas in the lower chamber. This creates a vacuum that draws water into the pipette. This means that the gas mixture in the bottle originally contained no CO2 at the beginning of the experiment, which is quite difficult to configure. Therefore, it is a rough measure of the use of O2, at best.
