living creature. Oxygen is used for plant growth and the development of new plants, seeds, leaves and shoots for example. Therefore, they also produce carbon dioxide as a'waste product' once the oxygen has been used. Plants do not photosynthesize through the night because there is no sunlight energy available to do that. So they only need carbon dioxide during the day for photosynthesis. This cycle of oxygen production and use, and carbon dioxide use and production, is very important to life on Earth. ACTIVITY: The oxygen and carbon dioxide cycle INSTRUCTIONS: 1. Carefully study the following illustration. 2. Answer the questions that follow. The oxygen and carbon cycle. 16 Life and Living
QUESTIONS: 1. Make a list of living organisms that produce both oxygen and carbon dioxide in this picture. 2. Identify three living organisms that cannot produce oxygen in this picture. 3. Predict what you think would happen if all the animals were removed from this habitat. 4. What two life processes are involved in the carbon dioxide/oxygen cycle? 5. Complete this cycle by filling in the missing information for the two arrows on the left hand side of the illustration. Supply the labels for arrows 1 and 2. 6. Explain why animals would not survive if all the plants on Earth were to suddenly die. Chapter 1. Photosynthesis 17
