1. Full Name – Today’s Poll question Homeroom What do you dip a chicken nugget in? Aims: SWBAT trace energy from the sun through an ecosystem by using food chains and an energy pyramid. Do Now: 1) What are decomposers? 2) Why aren’t vultures or humans decomposers? 3) Give one example of each of the following: Herbivore Carnivore Omnivore

2. Aims: SWBAT trace energy from the sun through an ecosystem by using food chains and an energy pyramid. Agenda: Entrance Procedures (7 min) Food Chains [I do] (10 min) Food Chains [We do] (10 min) Food Chains [You do] (20 min) Closing (5 min)

3. Do Now: 1) What are decomposers? Bacteria and fungi that eat dead organisms. 2) Why aren’t vultures or humans decomposers? We’re not decomposers because only tiny things can be decomposers! 3) Give one example of each of the following: Herbivore - Horse Carnivore - Wolf Omnivore - Bear

4. Hook What’s happening in this picture?

5. Food Chains [I do] _____________ are diagrams that show which organisms _______________. All food chains start with ________, then move to __________, and finish with ___________ and then ______________. Food chains eat each-other the sun producersconsumers decomposers

6. Food Chains [I do] Each step up the food chain there are ______ animals. (Giraffes eat a lot of grass, and a lion eats hundreds of giraffes over its life time). This is shown visually in an energy pyramid. Because energy is ____ in all transformations animals at the top of the food chain have to eat a lot more than the plants at the bottom. fewer lost

7. Food Chains [We do] 1. What is the mouse’s prey? 2. What is the mouse’s predator? 3. Where does the energy from the entire food chain come from? Grasshoppers Snakes The sun

8. Food Chains [We do] 4) What happens after the fish die? 5) Would the phytoplankton be able to survive without the algae? 6) What is the purpose of a food chain? They get eaten by the decomposer and repeat. No, they depend on the algae to survive. To show how energy moves through a ecosystem (what eats what).

9. Food Chains [We do] 7) These organisms are placed in an energy pyramid. Why are there so many plants but so few birds? Energy is lost (as heat) in every transaction. 8) Draw #7 as a food chain:

10. Exit Slip: 1) Why do carnivores at the top of the food chain have to eat so much more than herbivores at the bottom? 2) What is the source of almost all energy on earth? Homework: Food Chains Sneak Preview!__________________ Food webs
