The most likely change in air quality is a decrease in carbon dioxide (CO2) present in the box.
Photosynthesis is the process by which green plants produce their own food in the presence of light and carbon dioxide. The most important indicator of air quality is carbon dioxide. This gas is removed during photosynthesis.
This implies that after two days, analysis of the air samples from the pot will definitely indicate a large decrease in the amount of carbon dioxide present in the box.
Missing parts;
An airtight, temperature-controlled glass box containing actively growing tomato plants was placed under a lightsource. Plastic wrapping that only transmits green light was placed over the box, and two days later air samples frominside the box were collected and analyzed. The most likely change in air quality isa. an increase in nitrogen (N2)b. an increase in carbon dioxide (CO2)c. an increase in oxygen (O2)d. a decrease in carbon dioxide (CO2)
