  1. Monday January 4, 2010 Objectives – Chapter 13.1/3.2 Review – what did we learn before the break? Summarize levels of organization ecologists study Describe research methods of ecologists Bellwork – Write the letters A – Z down one side of your paper – write one thing you remember (word or phrase) about what we did before break.

  2. Tuesday January 5, 2010 Objectives – 13.3 Describe the roles of producers and consumers in ecosystems Compare photosynthesis to chemosynthesis Bellwork – How would the removal of a keystone species affect an ecosystem’s biodiversity? What are the five different levels of organization studied by ecologists?

  3. Test Next Tuesday! Wednesday January 6, 2010 Objectives – 13.4 Describe the structure of a food chain Explain how food chains and trophic levels are related Analyze feeding relationships in a food web Bellwork – How does the stability of an ecosystem depend on its producers? Few producers live deep below a lake’s surface. Suggest an explanation for this pattern.

  4. Quiz Wednesday Monday January 11, 2010 Objectives – Chapter 13.5 Summarize Earth’s hydrologic and biogeochemical cycles Relate cycling of matter to ecosystems Bellwork – What happens to energy as it flows through a food web? How might the stability of an ecosystem be affected if all of the decomposers were suddenly removed?

  5. Quiz Tomorrow Tuesday January 12, 2010 Objectives –13.6 Trace the flow of energy through an ecosystem, using an energy pyramid. Relate energy pyramids to food chains and trophic levels Compare and contrast a biomass and pyramid of numbers Bellwork – How does the hydrologic cycle move water through the environment?

  6. Quiz Today Test Tomorrow Wednesday January 13, 2010 Objectives – Go over homework Chapter 13 Quiz – do and go over Bellwork – How does an energy pyramid help to describe energy flow in a food web? If each level in a food chain typically loses 90% of the energy it takes in, and the producer level uses 1000kcal of energy, how much of that energy is left after the third trophic level?

  7. Test today Thursday January 14, 2010 Objectives – Ch 13 Test – 35 MC and 1 ORQ Bellwork – Turn to your neighbor and study for 5 minutes – look over your notes and quiz from yesterday.

  8. Friday January 15, 2010 Objectives – 17.1 Examine the scientific naming system developed by Linnaeus Identify the limitations of the Linnaean system Bellwork – How can we determine if two or more species are related? What would be a benefit of having a single system used for the naming of new species?
