An organism is sealed in a chamber. Scientists measure the amount of carbon dioxide and oxygen in the chamber. In 3–5 sentences, explain how they can use the volumes of these gases to determine if photosynthesis or cellular respiration is occurring in in the chamber. (4 points)

Answer 1

Scientists can determine whether photosynthesis or cellular respiration is occurring in the sealed chamber by measuring the relative amounts of oxygen and carbon dioxide over time. During photosynthesis, plants consume carbon dioxide and release oxygen, leading to a decrease in CO2 levels and an increase in O2 levels. Conversely, during cellular respiration, organisms consume oxygen and produce carbon dioxide, resulting in a decrease in O2 and an increase in CO2. By monitoring these changes, scientists can identify the dominant process taking place based on the gas concentrations.

Answer 2

i wrote this but i need one more sentence: If the volume of the carbon dioxide is decreasing while the oxygen volume is increasing, then photosynthesis is occurring. But if the carbon dioxide is increasing and the oxygen volume is decreasing, cellular respiration is occurring.
