Answer:
D
Explanation:
Animals and plants preform a process known as cellular respiration.
This process is:
oxygen+glucose--> carbon dioxide+ water + ATP (energy)
If a plant was placed in this container with carbon dioxide and oxygen, it would preform cellular respiration, but it would also use another process called photosynthesis:
carbon dioxide+water+light energy-->oxygen+glucose
Since a plant performs both, the levels of carbon dioxide and oxygen wouldn't change a lot.
However, if this was an animal, the carbon dioxide levels would increase. An animal would inhale oxygen, use it in cellular respiration, and then exhale carbon dioxide as a waste product.
Therefore, the correct answer is D: increase in carbon dioxide levels.
