Energy Flows 1. Imagine you find yourself on a newly formed island with no other life forms. Can you survive by yourself with no other life forms? Why or why not? 2. What other species would you need to survive? What types of interactions would you have with them? 3. In your table group cut out the organisms provided to you. Next, draw a line(s) IN PENICL between the organisms showing where energy is being transferred between organisms and what forms of energy are being transferred 4. All living things have a metabolism. What types of metabolism (respiration) do the organisms undergo? Autotroph: Heterotroph: 5. Label each organism as a heterotroph or an autotroph 6. What is the relationship between autotrophs and heterotrophs? 7. Match each type of nutrition to its definition: Herbivore_______________________ A. Consumes a diet of meat and plants Carnivore_____________________ B. Consumes a diet of only plants Omnivore_____________________ C. Consumes a diet of only meat Scavenger___________________ D. Eats a diet of dead animal and plant material 8. Label each organism on your diagram by its type of nutrition 9. Read the trophic level handout. Label the trophic level of each organism on your food web. And arrange the organisms by trophic level Write the animals you labeled in each level on the pyramid below Quaternary Consumers Tertiary Consumers Secondary Consumers Primary Consumers Primary Producers Decomposers Disrupting energy flows 1. Your teacher will provide you a set of new organisms that have immigrated into your ecosystem (set B). Add these organisms to your food web, labeling the metabolism, type of nutrition, and trophic level of each new organism 2. What is the trophic level(s) of the new set of animals? 3. What influence did the immigration of these organisms have in your ecosystem? 4. Would an ecosystem with more organisms in this trophic level than producers be sustainable over time? Why or why not? 5. Remove the species that were provided to you by your teacher. Your teacher will now provide you with a new set of organisms (set C). These organisms have now immigrated into your ecosystem. Add these organisms to your food web, labeling the metabolism, type of nutrition, and trophic level of each new organism 6. What is the trophic level(s) of the new set of animals? 7 What influence did the immigration of these organisms have in your ecosystem? 8. Would an ecosystem with more organisms in this trophic level than producers be sustainable over time? Why or why not? 9. Remove the species that were provide to you by your teacher. Now, remove all of the primary producers from your food web and answer the questions below. 10. What effect will the removal of primary producers have on your food web? 11. Will some trophic levels increase or decrease in size? Why or why not?
