Presentation Transcript

  1. #95 Warm UP Draw a food web with - at least 4 organisms - at least 1 autotroph - arrows going in the right direction • TAKE OUT • #7 & #8 Ecology and Human Impact Practice Packet

  2. Big Concepts in Ecology • Energy moves in one direction, constantly being added by the sun, it is NOT recycled • Materials (water, nutrients, carbon) cycle through an ecosystem • Abioticfactors are nonliving (water, light) • Biotic factors are living (predators) • Biotic and Abioticfactors keep populations from growing too big; all ecosystems have a carrying capacity • When organisms interact it can be positive or negative

  3. Big Concepts in Ecology • All stable ecosystems need more autotrophsthan heterotrophsAND they need decomposers to recycle nutrients back to soil • All stable ecosystems have high biodiversity • Each organism has its own niche, to avoid competition • Ecosystems that change suddenly usually return to their original state by succession, leading to a more stable community

  4. Key Terms • Heterotroph: eats its food • Autotroph: makes its own food • Decomposer: breaks down dead materials • Herbivore: eats only plants • Carnivore: eats only animals • Omnivore: eats both plants and animals

  5. Practice

  6. Practice

  7. Big Concepts in Human Impact • Most ecological problems are because of human overpopulation (due to better medicine, sanitation, and technology)

  8. Activity – Self Assessment • Score and correct your #7 & #8 REVIEW packet using the answer keys provided • As a table, Identify 2 questions from the packet: • 1 question you thought was extremely difficult, that you STILL do not understand • 1 question where you can explain the mistake you made and how to get the correct answer • Share on your easel (do not write out the question) Extension WORK ON VOCAB Study Island – Any Unit that you want to review

  9. Summary Let’s review any questions you have from the HW

  10. REFLECTION How does the removal or extinction of one species affect others in the ecosystem? HOMEWORK Regents Practice for LABS
