Ecology Review Key Principle: Law of Conservation of Mass and Energy

Stations 1.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 roles 6.Analyze the food web for energy flow AND label each members’ role.

Station # 1 AbioticBiotic 1. Define abiotic = ____________________________________ 2. Classify items as abiotic or biotic: water Snake skin wood bone flint cherry fruit Saber tooth tiger vertebra tree worms

Station # 2 AbioticBiotic 3. Define biotic = ____________________________________ 4. Classify items as biotic or abiotic: coal “empty” container Fossilized trilobites granite shells plant Volcanic pumice Volcanic pumice tarantula exoskeleton Fossilzed bone

Station 3: Levels of Organization Define the levels and create a 5 level biosphere beginning with the given organism – A ZEBRA!! Drawings 5. Organism = ___________ 6. Population = __________ 7. Community = _________ 8. Ecosystem* = _________ 9. Biosphere = ___________ * Don’t forget the abiotic factors!

Station # 4: Food Chains & Energy Flow 10. 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: sheep plant worm fly jaguar The Sun

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: giraffe insect little girl alligator zebra crab lion jaguar worm antelope spider

Station 6: Roles in Energy Pyramid 19. consumer = _____________ 20. producer = _____________ Classify the following as producers and consumers: spider plants chicken pig zebra elephant apple sheep camel rhinoceros fruit
