1. TWO PARTS: 1. RESERVOIR- LOCATION OF NUTRIENT 2. PROCESSES – MOVES NUTRIENT Biogeochemical Cycles The cycling of nutrients in the biosphere involves both matter in living organisms and physical processes found in the environment such as weathering.

2. Four Biogeochemical Cycles: Forms Nutrient Can Take On In Cycle Nitrogen Cycle nitrates, nitrites, ammonia, nitrogen, proteins Carbon Cycle carbon dioxide, glucose & other sugars, limestone (calcium carbonate), all organic compounds like fossil fuels (coal, methane) Water Cycle rain, snow, sleet, ice caps, salt water, fresh water, water vapor Phosphorus Cycle phosphates, rocks,

8. Phosphorus is the only cycle that does not have an atmospheric reservoir. PO 4 is known as phosphate. It Is a polyatomic ion. How do you know?

10. Principles of Ecology A diagram that can show the relative amounts of energy, biomass, or numbers of organisms at each trophic level in an organism Flow of Energy in an Ecosystem: Ecological Pyramids Rule of 10’s means that only 10% of the energy from a trophic level is passed on to the next trophic level. This applies to the Pyramid of Energy. Numbers decrease because level energy available as go up trophic levels

11. Biogeochemical Cycles Diagram Reading Complete the Cycle Diagram Worksheets. As you complete them, pay close attention to the process and the reservoir. Be sure you know why each cycle is important for life. Remember, nutrients cycle and energy flows. Section 2.3 and Ecological Pyramids Quiz: Wed, 11/11
