In the process of photosynthesis, plants take in carbon dioxide (CO2) from the atmosphere and water (H2O) from the soil. Using the energy of sunlight, plants build molecules of glucose (C6H12O6) and oxygen (O2). Make sure all of your answers are in a different color. 1. How do plants on Earth affect the amount of carbon in Earth’s atmosphere? 2. Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth’s atmosphere? Gizmo Warm-up The Carbon Cycle Gizmo allows you to follow the many paths an atom of carbon can take through Earth’s systems. To begin, notice the black carbon atom in the Atmospheric CO2 area, highlighted in yellow. T he glowing blue areas represent possible locations the carbon atom could go next. 1. From Earth’s atmosphere, where can the carbon atom go next? 2. Click on Land plants and read the description (at the bottom of the simulation). How did the carbon atom get from the atmosphere to a plant? 3. Select Land animals. ...
