Biogeochemical Cycles



Biogeochemical Cycles SC.912.E.7.1 Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.Essential Question: How does the movement of matter and energy through biological systems impact you?________________ flows through organism and ecosystems. As energy travels through different trophic levels ________ % of it is emitted into the atmosphere.What about nutrients?Nutrients _______________________.nutrients must be _________________________________ to be available for the next generation___________________________________________ return nutrients to the soil after creatures dieFungi_____________________Nutrients ______________________________ around through decomposersEnergy ________________________________ and nutrients ____________________________The Water cycleThe movement of water from the ground to the _________________________ and back againWater gets to the atmosphere by: Evaporation – heat from the ________________________________ – movement of water through a plantsSublimation – snow and ice ___________________________ to water vaporWater leaves the atmosphere by:_____________________________ - water vapor in the air is changed into liquid water (formation of clouds)Precipitation - water ________________________ from clouds in the form of rain, freezing rain, sleet, snow, or hail.Disruptions in the Water Cycle Why would we need government policy to limit human impact on the water cycle? Describe policies (laws/rules) related to the water cycle you may know about.How could changes in the water cycle impact YOU? The Carbon cycleCarbon is present in the ___________________________ as Carbon Dioxide: Volcanic _____________________Respiration__________________________________Burning fossil fuelsDecomposition of _________________ material. Plants, producers, ________________ CO2 from the atmosphere for photosynthesis and release O2Convert solar energy into ____________________ energy Animals, consumers, remove O2 from the atmosphere for cellular ________________________ and release CO2Convert chemical energy in plants to ______________ energyDisruptions in the Carbon Cycle Why would we need government policy to limit human impact on the carbon cycle? Describe policies (laws/rules) related to the water cycle you may know about.How could changes in the water cycle impact YOU? ................
