  1. Essential Questions • What are the implications of interconnectedness? • How does understanding interconnectedness affect perception?

  2. 1st law & food webs

  3. 1st Law: Everything is connected to everything else Making connections: What is the connection between the rise of McDonalds outlets in China and the massive deforestation in the Amazon forest in Brazil? 2. Take the Carbon footprint test: http://footprint.wwf.org.uk/

  4. http://footprint.wwf.org.uk/

  5. Activity:Web Game PART 1: Getting organized • Get assigned card. • On your island work together to figure out: • What is your role in nature? • How can you survive? 3. Discuss vocabulary. 4. As a class, group yourselves according to similarities based on your role in nature.

  6. Autotroph / primary producer • Makes it’s own food (glucose) from primary energy source (sun or deep-sea thermal vents) • Use photosynthesis or chemosynthesis • PPP: A plant = producer = photosynthesis

  7. Heterotroph/ consumer • Cannot make their own food • Must eat other living organisms http://scratch.mit.edu/projects/mrshart/933775

  8. Herbivore or primary consumer • Eat producers • Folivore (leaves) - frigivore (fruit) • granivore (seed) - mucivore (sap) • necativore (nectar) -palynivore (pollen) • xylophage (wood)

  9. Secondary- quarternary consumers • Eat consumer level below them • Carnivore = meat-eaters • Omnivore = eat animals and plants (like 1⁰ consumers do) • Predator- the animal doing the hunting & eating • Prey- the animal being hunted & eaten

  10. Top/ Apex predator • The top-end of the food chain • Is not eaten by anything else (is not prey) because it has little/no natural predators* * Humans often not consider natural predators

  11. Detritivores • Eat detritus: plant and animal remains, shed parts (skin, antlers, leaves), and wastes • Scavengers- detritivores that specialized in carrion (dead animal bodies) or other animal wastes

  12. Decomposers (aka saprotrophs) • digest food outside their bodies • Fungi eat the dead matter by releasing acid found in their body to melt the decaying material, then sucking in all the acid, along with the melted material • Help speed up the decaying process Cool fact: A gram of soil typically contains 40 million bacterial cells, and the bacteria on Earth form a biomass that exceeds that of all living plants and animals

  13. Activity:Web Game PART 1: Getting organized • Get assigned card. • On your island work together to figure out: • What is your role in nature? • How can you survive? 3. Discuss vocabulary. 4. As a class, group yourselves according to similarities based on your role in nature.

  14. PART 2: Making the web Individual Goal: Find a way to survive • Using string, connect yourself to all possible food sources e.g. horse eats the grass  grass “eats” the sun (string connects horse to grass and same string connects grass to sun; cut string to indicate end of chain) Note: Use 1 string per food source

  15. The difference between webs and chains

  16. top predator

  17. PART 2: Making the web Individual Goal: Find a way to survive • Using string, connect yourself to all possible food sources e.g. horse eats the grass  grass “eats” the sun (string connects horse to grass and same string connects grass to sun; cut string to indicate end of chain) Note: Use 1 string per food source

  18. PART 3: Changes in the web Goal: Find out how species affect each other • What happens when one species is removed? • producer b. consumer(type) c. decomposer • What happens when there are changes with the “SUN”?

  19. REFLECTION: What are the implications of interconnectedness? • What happens when one species is removed? • producer • consumer-omnivore/ carnivore/ herbivore • decomposer • What happens when changes with the “SUN” happens?
