Using a water filled manometer you observed the amount of oxygen consumed by rats in a sealed chamber. what happened to the carbon dioxide the rat produced while in the sealed chamber?

In a sealed chamber, the rats consume oxygen and produce carbon dioxide as a byproduct of respiration. The carbon dioxide accumulates in the chamber since there is no exchange with the external environment. As oxygen levels decrease and carbon dioxide levels increase, the pressure changes can be measured using the water-filled manometer, indicating the metabolic activity of the rats. Ultimately, the manometer reflects the balance of gases in the chamber, showing the consumption of oxygen and the production of carbon dioxide over time.
