Vika [28.1K]

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!

How does photosynthesis help to maintain homeostasis in plant cells?
viktelen [127]

Plants maintain homeostasis by keeping their stomata open just enough to allow photosynthesis to take place but not so much that they lose an excessive amount of water.

When plant cells use the food they make, the cells respire, taking in oxygen and giving off carbon dioxide.

- Hope this helps
