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. Write like a student.

Answer 1

Scientists can analyze the volumes of carbon dioxide and oxygen in the chamber to determine the processes happening within the organism. If they notice an increase in oxygen levels and a decrease in carbon dioxide levels, it suggests that photosynthesis is taking place, as plants consume CO2 and release O2. Conversely, if the carbon dioxide levels rise and oxygen levels drop, it's likely that cellular respiration is occurring, where the organism is using O2 and producing CO2. By measuring these gas levels over time, researchers can understand which process is dominant in the chamber.
