Biogeochemical Cycles Bio = Life Geo = Geological Processes Chem = Chemical Processes Water Cycle Carbon and Oxygen ▫Short Term ▫Long Term #1 ▫Long Term #2 Nitrogen Cycle Phosphorus Cycle ▫Short Term ▫Long Term
Carbon and Oxygen Cycles Short Term Cycle: ▫Photosynthesis and Cellular Respiration Long Term Cycle #1: ▫Organic matter is buried and become fossil fuels. CO 2 is released back into the atmosphere when fossil fuels are combusted (burned) Long Term Cycle #2: ▫Calcium carbonate is found in shells of sea animals. When they die, the shells go to the bottom of the ocean to create limestone rock. Carbon and oxygen are trapped until weathering and erosion release these elements back into water and the atmosphere.
Project Application Include these two biogeochemical cycles on your island.
