ch 5 key concepts

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 *
