Question

In our experiment with super worms and'pill bugs, we observed

respiration. Identify the gas that was produced. How did we measure

this gas?

Answer

The gas produced during respiration is carbon dioxide (CO2). We can measure this gas using a carbon dioxide sensor or by using a pH indicator solution that changes color in the presence of CO2.

During respiration, organisms consume oxygen and produce carbon dioxide as a waste product. In the case of the super worms and pill bugs, they were likely producing carbon dioxide as they were respiring. To measure the amount of carbon dioxide produced, a carbon dioxide sensor can be used. This sensor detects the concentration of carbon dioxide in the air and provides a reading. Alternatively, a pH indicator solution can be used. When carbon dioxide dissolves in water, it forms carbonic acid, which lowers the pH of the solution. By measuring the change in pH of a solution over time, we can estimate the amount of carbon dioxide produced. Both methods can be used to measure the amount of carbon dioxide produced during respiration in organisms.
