  1. BiogeochemicalCycles Mr. Skirbst Life Science Topic 19

  2. Cycles

  3. Cycles Daily Rhythms

  4. Cycles Daily Rhythms diurnal – active at day

  5. Cycles Daily Rhythms diurnal – active at day nocturnal – active at night

  6. Cycles Lunar Rhythms

  7. Cycles Lunar Rhythms tides – high / low monthly cycles

  8. Cycles Annual Rhythms

  9. Cycles Annual Rhythms seasonal changes

  10. Cycles Annual Rhythms seasonal changes migration – annual movement from breeding to feeding grounds

  11. Cycles Annual Rhythms seasonal changes hibernation – winter resting state (Latin: hibernus – “winter”)

  12. Cycles Annual Rhythms seasonal changes estivation– summer resting state (Latin: aestivus– “summer”)

  13. Cycles of Matter Flow of matter (chemicals) from non-living (abiotic) to living (biotic) parts of an ecosystem, and back again

  14. Cycles of Matter Water Cycle: - evaporation (liquid to gas)

  15. Cycles of Matter Water Cycle: - evaporation - condensation (gas to liquid) (cloud formation)

  16. Cycles of Matter Water Cycle: - evaporation - condensation - precipitation (rain, snow, sleet, hail, fog)

  17. Cycles of Matter Water Cycle: - evaporation - condensation - precipitation - infiltration / runoff (groundwater, streams, oceans)

  18. Water Cycle

  19. Cycles of Matter Oxygen – Carbon Cycle:

  20. Cycles of Matter Oxygen – Carbon Cycle: - photosynthesis (producers: take CO2 O2)

  21. Cycles of Matter Oxygen – Carbon Cycle: - photosynthesis (producers: take CO2 O2) - respiration (consumers: take O2  CO2)

  22. Carbon – Oxygen Cycle

  23. Cycles of Matter Nitrogen Cycle:

  24. Cycles of Matter Nitrogen Cycle: - fixation: bacteria change “free” N from air to N-compounds in soil

  25. Cycles of Matter Nitrogen Cycle: - metabolizing: N-compounds moved from soil to plants to animals

  26. Cycles of Matter Nitrogen Cycle: - decomposition: bacteria “free” N back to air again

  27. Nitrogen Cycle

  28. Cycles of Change Ecological Succession: - gradual change from one community to another

  29. Cycles of Change Ecological Succession: - gradual change from one community to another Climax Community:

  30. Cycles of Change Ecological Succession: - gradual change from one community to another Climax Community: - a stable community of organisms

  31. Cycles of Change Ecological Succession:
