• Key Principle: Law of Conservation of Mass and Energy

Stations1. Abiotic or Biotic?2. Biotic or Abiotic?3. Create a Biosphere with 5 levels of organization

starting with the given organism.4. Create food chain and add arrows for energy

flow.5. Create a food chain and identify the roles6. Analyze the food web for energy flow AND label

each members’ role.

Station 3: Levels of OrganizationDefine the levels and create a 5 level biosphere beginning with the given organism – A ZEBRA!! Drawings5. Organism = ___________6. Population = __________7. Community = _________8. Ecosystem* = _________9. Biosphere = ___________

* Don’t forget the abiotic factors!

Station # 4: Food Chains & Energy Flow10. Create a food chain/ web with the abiotic and biotic factors on the tray.11. Add arrows to show the energy flow.

12.What is the main source of energy of for most food chains on the surface of the earth? ______________13.What is the main source of energy for most food chains near oceanic vents?Go to: http://www.youtube.com/watch?v=D69hGvCsWgA

Station 5:   Roles in a Food Web - Define and classify the items on the tray as the following:

14. detritivore = _____________________________________________ 15. herbivore = ______________________________________________ 16. Carnivore = ______________________________________________ 17. omnivore = ______________________________________________ 18.Create a wacky food chain/ web of the organisms based on their: roles:
