Question

Quizplus · Accepted Answer

The decrease in carbon dioxide levels in the closed chamber is an indicator of photosynthesis. During photosynthesis, plants take in carbon dioxide from the air and use it to make glucose and oxygen. As a result, the concentration of carbon dioxide in the closed chamber will decrease. Cellular respiration, sucrose production, and alcohol fermentation all involve the production or consumption of carbon dioxide, but they would not cause a decrease in the concentration of carbon dioxide in the chamber. Fertilization is the union of gametes and would not affect carbon dioxide levels.
