Mr. Moraliev wanted to find out how much carbon dioxide is used up by a plant. He placed the plant in a sealed glass container filled up with 3 liters of carbon dioxide. He then varied the time a plan spent in sunlight and measured the change in the CO2 levels in the container. The change in carbon dioxide over time is the...
