  1. ECOLOGY CRAM SESSION: Biology EOC at SCHS • the study of how organisms interact with their environment

  2. Biotic vs. Abiotic Factors • BIOtic = is or was alive • Abiotic = not alive (never was or will be) alvie

  3. FA: abiotic or biotic? 2 1 3.b 3.a 4 5 Leather jacket

  4. Energy Pyramid • Top predator • Secondary consumer • Primary consumer • Producers/autotrophs

  5. Trophic Levels • Trophic levels -hierarchical levels in an ecosystem • always start at the bottom of the energy pyramid with trophic level & count upward Trophic levels are DIFFERENT from consumer levels!! 4 3 2 1

  6. Ask questions: consumer/trophic level

  7. Carrying Capacity • max population size an area can support (with enough density dependent factors) • density-dependent factors are______

  8. Test Taking Strategies • does the question say “best,”“most correct”“not,” or “all”bold? PAY ATTENTION!!!! • You may not know what the answer IS, but you may know which choices are NOT the answer! • Choose an answer that answers the question! • If answers have a “,”“and:”BOTH statements before and after the “,”“and” must be correctfor the statement to be the answer!

  9. Which of the following descriptions about the organization of an ecosystem is correct?a. Communities make up organisms, which make up populations.b. Populations make up ecosystems, which make up communities.c. Organisms make up communities, which make up populations.d. Organisms make up populations, which make up communities.

  10. Break for students to work on page 1 questions • 1. B • 2. C • 3. C • 4. B 5. C 6. A 7. B

  11. Carbon Cycle • Carbon cycles as ____ • Which 2 processes cause carbon to recycle on Eath?

  12. Nitrogen Cycle • Nitrogen recycles because of ____ & bacteria in the soil

  13. Symbiosis Relationships B • 1.which is mutualism? 2. parasitism? • 1. B 2. A A

  14. habitat/home Habitat vs. Niche Niche-organisms role; where lives, hunts, predator, prey habitat/home

  15. Non-Native/Invasive Species • any organism brought into an area to live (not naturally found there) HYBRID Japanese Lady Bug NC Lady Bug What issues are caused? http://www.youtube.com/watch?v=iLH1qLCvqSg Kudzu

  16. Predator/Prey Relationship • How does a predator population effect its prey population?

  17. Human Impact • depleting natural resources • pollution (acid rain, carbon, water, air, and nitrogen) • habitat destruction & depletion • deforestation (carbon cycle)

  18. Break for students to work on page 2-3 questions • 8. B • 9. B • 10. C • 11. B • 12. A 13. A 14. D 15. B 16. A 17. A 18. A 19. A
