Name: Date: Format responses in blue bold font. Student Exploration: Carbon Cycle Vocabulary (refer to vocab file located on the Gizmo site for definitions): Atmosphere: the gases that surround a planet Biomass: the total mass of a group of living things. Biosphere: living things on a planet. Carbon reservoir: a part of Earth that stores carbon Carbon sink: a carbon reservoir that absorbs carbon from the atmosphere and stores it for a long period of time fossil fuel: a fuel formed over thousands or millions of years from the remains of living organisms Geosphere: the rocky, non-living parts of a planet. Greenhouse gas: a gas in Earth’s atmosphere that absorbs and then re-radiates heat. Hydrosphere: – the water on a planet. Lithosphere: the rigid upper layer of the Earth Photosynthesis: – a process in which plants use energy from light to change carbon dioxide and water into glucose (sugar) and oxygen Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 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). 1. How do plants on Earth affect the amount of carbon in Earth’s atmosphere? The plants take in carbon from the air for photosynthesis. It decreases the amounts of carbon levels in the air. 2. Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth’ ...
