  1. Standard 2 Part 2: How Ecosystems Work

  2. Bell Ringer, 9/4 • Get your TRIBE POINTS • Get out your Squirrel Island hand out and drawing • On your bell ringer paper, answer the following question: • How can organisms adapt to the environment? • Why do organisms need to adapt to the environment?

  3. Bell Ringer, 9/5 • Get your TRIBE POINTS • Get ONE manilla folder per tribe (on the middle lab table) • On your bell ringer, list each of the types of interactions between organisms and define it IN YOUR OWN WORDS (yes, this is in your notes!)

  4. Tribe Scribes: Write each type of interaction on a slip of paper

  5. Types of Interactions • Predation • Parasitism • Competition • Commensalism • Mutualism

  6. Charades!

  7. Folder Decoration Time • You have TEN MINUTES to create an awesome folder for your tribe!!! • The tribe with the coolest folder will win an extra 50 points for their tribe!

  8. Energy Flow in Ecosystems • Life depends on the sun • Plants, algae, and some bacteria capture energy from the sun (photosynthesis) • They use this energy to produce sugar, an energy-rich food

  9. Energy Flow in Ecosystems • Producer: Organism that makes its own food • Plants, bacteria, algae • Also known as autotrophs • Consumer: Organism that eats other organisms to get food • Animals, fungi • Also known as heterotrophs

  10. Energy Flow in Ecosystems • Almost all organisms get their energy from the sun • Producers get their energy directly from the sun • Consumers get their energy indirectly from the sun through producers

  11. Energy Flow in Ecosystems • Exception: Deep sea ecosystems • Exist in total darkness (no sunlight for photosynthesis) • Get energy from deep sea vents • Bacteria use energy from the vents to make food

  12. THE GREAT PAPER ROUND UP • Put your papers in the correct section of your binder! • Bell Ringers and Exit Slips • Drawings, vocab, worksheets: Practice • Hour Log, graphic organizers: Class Info/Study Skills IN ORDER TO TAKE YOUR TEST YOUR BINDER WILL HAVE TO BE COMPLETE.

  13. Bell Ringer, 9/5 • Get your tribe’s POINTS FOLDER and POINTS • If you have any work to turn in, put it in your tray • Put your SQUIRREL ISLAND CHART in the tray • On your bell ringer paper, answer the following question: • Do all organisms get their energy from the sun? Defend your answer.

  14. Bell Ringer Follow Up • TEACH your neighbor about the answer to the bell ringer!

  15. IMMUNITY CHALLENGE • Immunity challenge has been CANCELLED for this week, due to parent/teacher conferences and the holiday • The next immunity challenge will be NEXT FRIDAY • Sorry… These things happen 

  16. Energy Flow in Ecosystems • Types of consumers: • Herbivores: Eat plant matter only • Carnivores: Eat the meat of other animals only • Omnivores: Eat both and plant and animal matter • Decomposers: Break down dead organisms

  17. What type of consumer is it?

  18. Energy Flow in Ecosystems • In your notes, draw a picture representing each type of consumer! • You have FIVE MINUTES!

  19. Test Return Time! • Any questions?

  20. Energy Flow in Ecosystems • Food chain: Sequence in which energy is transferred from one organism to the next as each organism eats another • GrassCaterpillarBirdFox

  21. Energy Flow in Ecosystems

  22. Energy Flow in Ecosystems • Let’s make one together!

  23. Energy Flow in Ecosystems • In the MARGIN of your notes, create your own food chain! • You have FIVE MINUTES

  24. Energy Flow in Ecosystems • LABEL each organism is your food chain: • P = producer • H = herbivore • O = omnivore • D = decomposer • C = carnivore

  25. Energy Flow in Ecosystems • Trade your food chain with a neighbor • See if you agree with your neighbor’s food chain • If so, draw them a nice smiley face • If not, present it to your tribe. If you can’t all agree, raise your hand and we will talk about it. • Once you reach a consensus, draw them a nice smiley face

  26. Energy Flow in Ecosystems • Real ecosystems are more complicated than just one food chain • Food Web: Diagram that illustrates all the food chains in an ecosystem

  27. Food Chains

  28. Let’s Try It!

  29. Folder Time • DECORATE your FOLDER • You have TEN MINUTES

  30. Exit Slip, 9/6 • Create a FOOD CHAIN with AT LEAST three organisms • Label each organism correctly • Pick an organism that could fit in A DIFFERENT FOOD CHAIN and use it to create a mini food web

  31. Bell Ringer, 9/9 • Get your tribe’s FOLDER and POINTS • On your bell ringer paper, answer the following question: • Draw a food chain and label all of the organisms • Use your food chain to create a food web

  32. Energy Flow in Ecosystems • Let’s make a food web!

  33. Energy Flow in an Ecosystem • Let’s draw it!

  34. Energy Flow in Ecosystems • Trophic level: Each step in the transfer of energy through an ecosystem • Each step of a food chain is one trophic level • Only about 10% of the energy at each trophic level flows to the next level

  35. Energy Flow in Ecosystems

  36. Energy Flow in Ecosystems • Energy loss results in: • Fewer organisms at the higher trophic levels • Limited number of trophic levels in an ecosystem

  37. Let’s try it!

  38. You try it!

  39. Tests and Folders

  40. Exit Slip, 9/9 • Create a food chain with at least 4 organisms • Correctly label each organism • Show the energy amounts passed to each organism

  41. Bell Ringer, 9/10 • Get your Exit Slips (2nd lab table) • Get your points and your folder • Answer the following questions: • Why is energy lost as it moves up the trophic levels? • How much energy moves to the next trophic level?

  42. Folder Decoration Time! (Finally)

  43. Let’s talk about notes.

  44. The Cycling of Materials • Most non-living materials in an ecosystem cycle • There are three cycles that we will study in this class: • Water Cycle • Carbon Cycle • Nitrogen Cycle

  45. The Cycling of Materials • The Water Cycle • Sun provides the energy that drives the water cycle • Heat from the sun evaporates water (evaporation) • Water vapor cools in the atmosphere (condensation) • When water vapor is heavy enough, it falls back to earth (precipitation) • Water runs off into streams or is absorbed by soil and becomes ground water

  46. Let’s Draw It!

  47. Let’s Watch It! • http://www.youtube.com/watch?v=FAnDlYRycqs&list=PLOoWeOpoaCHySa2kVvRQ8DkDbbJLoR0nH • Get scraps of paper and write on them: • Evaporation • Condensation • Runoff • Precipitation

  48. Act It Out! • As a tribe, come up with a good way to act out the water cycle. Get creative! The tribe with the best representation of the water cycle will get 50 points for their tribe! • Must include: • All reservoirs • All means of movement GOOD LUCK!
