  1. Ecosystems

  2. Question to Reading • What is an ecosystem? • Why is it healthier for an ecosystem to have lots of species diversity (different types)? • What would happen in a Lake if the algae disappeared? • What are the three categories of living organisms and define each? • What are the three types of consumers and define each? • What are the major parts of an ecosystem and define why each is important?

  3. Answers • What is an ecosystem? • “…is a community of living and non-living things that work together” (Ecosystems). • Why is it healthier for an ecosystem to have lots of species diversity (different types)? • “ ...less likely to be damaged by human interaction, natural disasters, or climate changes” (Ecosystems). • What would happen in a Lake if the algae disappeared? • Everything would be affected = death

  4. Answers Continue • What are the three categories of living organisms and define each? • Producers: make their own food • plants • Consumers: get their energy from producers or organisms that eat producers • animals • Decomposers: “… plants and animals that break down dead plants and animals into organic materials that go back into the soil” (Ecosystems).

  5. Answers Continue • What are the three categories of living organisms and define each? • Herbivores: eat planets • Carnivores: eat meat • Omnivores: eat planets and meat

  6. Answers Continue • What are the major parts of an ecosystem and define why each is important? • Soil: nutrients, anchors, absorbs and holds water • Atmosphere: oxygen and carbon dioxide, part of the water cycle • Heat and light: energy – photosynthesis, warmth, helps keep the water cycle going • Water: large % of what cell are made up of, used to carry and distribute nutrients • Living organisms: help keep each other alive and thriving

  7. Living vs. Non-living

  8. Explain the difference between a rock and a wooden plank. Include such things as physical make up and hot it was made.

  9. Abiotic • Non-living • Never has been alive

  10. Biotic • Living or has lived

  11. Venn Diagram of Biotic vs. Abiotic

  12. Continue: Venn Diagram of Biotic vs. Abiotic • What are things that could go into the intersection of these two circles? • Matter • Energy • Atoms

  13. 6 Characteristics that living this have in common • Growth • Reproduction • Respiration • Complex chemical reactions • Dissolving and transportation of material throughout a system • Digestion, metabolism, or the chemical reaction that causes a muscle to contract • Cells • Movement
