A device that records the amount and rate of air that is breathed in and out over a period of time is called a:

roponents of the potometer method of measuring transpiration rate used this to argue that dendrometers cannot accurately determine transpiration rate in trees. Which of the following could account for the lower readings of the potometer?AThe air surrounding the potometer plant cutting had a far lower humidity than the air surrounding the plants measured by the dendrometer.BThe potometer and dendrometer were measuring the transpiration rate of the same species of plant.CThe capillary tube had a larger diameter than the volume scale was calibrated to.
