Gizmos Student Exploration: Carbon Cycle Answers Key 2023
Gizmos Student Exploration: Carbon Cycle Answers Key 2023. How do plants on Earth affect the amount of carbon in Earth’s atmosphere? Plants absorb a great part of the carbon dioxide produced for them to do photosynthesis, so the levels of CO2 that raises to the atmosphere decrease in comparison to the production of it. 2. Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth’s atmosphere? Animals exhale carbon dioxide, a major part of it is consumed by the plants of the environment, but a part manages to raise to the atmosphere. Through food chains, animals eat or absorb the carbon dioxide found in plants or animals. 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. The glowing blue areas represent possible locations the carbon atom could go next. 1. From Earth’s atmosphere, where can the carbon atom go next? The carbon atom goes to the oceanic CO2. 2. Click on Land plants and read the description. How did the carbon atom get from the atmosphere to a plant? Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food. 3. Select Land animals. How did the carbon atom get from land plants into the animals? Through food chains, land animal eat plants or animals that also eat plants, the carbon dioxide they store moves to the animal. 4. Select Atmospheric CO2. How did the carbon atom get from land animals back to the atmosphere? In the process of cellular respiration, animals and plants break down glucose to produce energy, releasing carbon dioxide and water into the atmosphere.
