Join us for an engaging session on the carbon cycle, its impact on the ecosystem, and how mathematical representations can explain matter cycling. Test corrections, warm-up questions, and interactive lectures await, so grab your portfolio and delve into the world of carbon cycling!
E N D
Monday, October 30 Ecology - HS-LS2-4 I will be able to use mathematical representation to explain how matter cycles in the ecosystem Grab your portfolio! • Today’s agenda: • Test correction • Review of carbon cycle • Warm up questions • Mini-interactive lecture • Practice (Modeling and use mathematical representation)
Use this diagram to write THREE claims that explain how carbon gets recycled
Carbon/Oxygen cycle • Plants use CO2 for photosynthesis and release O2 in the process • Animals use O2 during cellular respiration and release CO2
Plants Use Carbon Dioxide • When plants use carbon dioxide for photosynthesis, the carbon becomes part of the plant (stored food). • Animal eat the plants and get the carbon dioxide
Plants and Animal Die • When plants and animals die, most of their bodies are decomposed and carbon atoms are returned to the atmosphere. • Some are not decomposed fully and end up in deposits underground (oil, coal, etc.).
Carbon in Rocks and Oceans • Carbon in rocks and underground deposits is released very slowly into the atmosphere (it takes years). • Additional carbon is stored in the ocean (largest store of carbon). • Many animals pull carbon from water to use in shells, etc. • Animals die and carbon substances are deposited at the bottom of the ocean.
Human Impact • Fossil fuels release carbon stores very slowly • Burning anything releases more carbon into atmosphere — especially fossil fuels • Increased carbon dioxide in atmosphere increases GLOBAL WARMING • Fewer plants mean less CO2 removed from atmosphere
