Transcript

  • 1. APES: Key Ideas for Chapter 5 (Biogeochemical Cycles) 1. macro vs micronutrients: know difference and a some examples 2. What are the Big 6 macronutrients? 3. Understand how any of these can be limiting factors. Know how that would impact growth or survival. 4. Elements with a gaseous phase vs. those with no gaseous phase: Compare the speed of cycling * 5. What 4 groups of cycles make up the larger geologic cycle? 6. Remember how to calculate ART ( there will be a few problems) 7. Nitrogen cycle: Know all the steps of the nitrogen cycle, what anthropogenic activities may bring them out of balance * 8. Carbon Cycle: Remember the formulas for photosynthesis and cellular respiration, since they are very important to cycling of carbon * What anthropogenic activities may bring the carbon cycle out of balance * 10. Water cycle, major energy source that drives it is the sun (evaporation) and understand the power of water erosion to release other nutrients locked in soil….* 11. Rock cycle, major energy source is tectonic movement 12. carbon-sylicate cycle, relationship to CO2 and Calcium carbonate (marine organisms shells), they die and sink, burial, high pressure subduction , volcanic re-release of CO2 from melted ocean sediments (see pg 93) 12. Eutrophication: what it is, examples, process *
