Thursday, Apr. p. 258, 259 rd 23 258 4/23/15 Thurs. L.T.: I can explain how yesterday’s demo is a model of cellular respiration and I can prepare for the test tomorrow. DO NOW: How does the demo from yesterday model cellular respiration? ………………………….. Reflection: What topics on the test am I still unsure of? What do I need to do tonight to fully prepare for this test? 259 Title: Test Prep Day PS Scratch paper Notecard taped in Thursday, Apr. 23rd RS • As you watch the video clips, please add notes about: • - How each function works • - Who uses these functions • - How they connect with energy flow in ecosystems PS/RS • Ecosystem Parts: (LS2A) • - individual, populations, communities, ecosystems, abiotic factors • • • • • Energy Flow in an Ecosystem: - food webs: feeding relationships (LS2B) - trophic levels: producers, consumers, decomposers (LS2B) - 10% rule: biomass pyramid (LS2B) - PS/RS: how energy enters and leaves an ecosystem (LS2C) Test Study Guide Consumers Population Biotic Secondary consumers Heterotrophs Organisms What ecosystem descriptions could we apply to these frogs? • Make a 6 part food chain from Mono Lake. Organize this food web into trophic levels • How do abiotic factors affect organisms? 1. What trophic level does the snake belong to? Why? 2. Let’s say the grasshopper and the frog both need 10 food items daily to survive. How many blades of grass are needed to support 1 frog? Why?. • Explain the crucial role that producers play in an ecosystem. • How do plants make their own energy? • Organize the following words into categories: 1. Herbivore 2. Primary consumer 3. producer 4. decomposer 5. detritivore 6. carnivore 7. omnivore 8. secondary consumer 9. top predator 10. photosynthesis 11. respiration 12. heterotroph 13. autotroph 14. consumer This is an individual CA gull. Can it also be a population? Why or why not? • Explain the relationship between photosynthesis and respiration. • What is the difference between decomposers and detritivores? • What trophic level do decomposers belong to? • Explain how both 1 square foot of Stewart’s lawn and the Puget Sound can both be considered an ecosystem.
