This worksheet reinforces the relationship between photosynthesis, cellular respiration, and the biogeochemical cycles. I was tired of asking students questions and getting the answer "air" instead of oxygen or carbon dioxide. This worksheet will allow students to visualize the amount of each gas in the atmosphere with a pie chart, and then answer questions about who removes these gases, who releases them, and through which processes.
