Can someone please help me with this question

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.

I hope this helps :)

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed

answer: 45
