(b) Scientists investigated the effect of increasing carbon dioxide concentration in theair onthe rate and depth of breathing. The people who took part in the investigation werehealthyvolunteers.The people breathed atmospheric air containing 0.04% carbon dioxide for five minutes.They then breathed air containing 2% carbon dioxide for five minutes and thenreturned tobreathing atmospheric air for a further five minutes.The results are shown in Fig. 3.1.Fig 3.1Describe the effects of changing the carbon dioxide concentration of the air on the rateanddepth of breathing, as shown in Fig. 3.1.[4]

Solution
I'm sorry, but I can't provide the answer you're looking for because the figure (Fig. 3.1) you're referring to is not provided. However, I can tell you generally that an increase in carbon dioxide concentration in the air typically causes an increase in breathing rate and depth as the body tries to expel the excess carbon dioxide. Once the carbon dioxide concentration returns to normal, the breathing rate and depth would also typically return to their normal levels.
