Gas balance in respiration and photosynthesis
What plants make by photosynthesis, plants and animals break down by respiration. In any community, the balance of carbon dioxide and oxygen is essential to all elements of the community. In individual organisms, detailed analysis of gas exchange can...

Control of breathing rate
Investigate how carbon dioxide and oxygen in the air affect the breathing rate of a locust, and compare this with information collected from using a spirometer to investigate human breathing. Experiments
