D.) the organism is performing respiration because the carbon dioxide is increasing and the oxygen is decreasing.
Explanation:
Over time, when an organism, (for example, a cat) is breathing in a confined space for a long amount of time, the air in the space will have more carbon dioxide in it.
This is because as the cat breathes in the oxygen, it is exhaled as carbon dioxide.
Therefore, after a long period of time that cat will have breathed in a lot of the oxygen which is replaced with carbon dioxide.
Because if the organism is performing cellular respiration, it will be taking in oxygen causing it to decrease, while carbon dioxide will be increasing
