Well I do know the answer to question #5 is temperature
Answer:
The correct option is C: "Oxygen levels would be higher, but carbon dioxide levels would be the same".
Explanation:
The sealed aquarium is paced near a window which means they have access to sunlight, and hence, can photosynthesize. As the plants use up carbon dioxide during the day and give out oxygen during this process, they also respire during the night, a product of which is carbon dioxide. This is why the levels of carbon dioxide will remain the same and level of oxygen will rise because they are photosynthesizing for a longer period during the day than they are respiring during the night.
Hope that answers the question, have a great day!
Human and the natural ones can change the ecosystem
