1. Do Now: Get out homework, notebook, and a pencil
A frog, a beetle, grass, a snake, and a hawk
Place each of the above into a food chain AND label each as a producer, first level consumer, second level consumer, third level consumer, or fourth level consumer

2. Engage Video

3. Glue this page on the BOTTOM of page

4. Notes go on page 49 Third role organisms play:
Decomposer- break down detritus (biotic wastes and dead organisms) and return it back into the ecosystem
Without them the energy in dead organisms would stay trapped
Examples are mushrooms, bacteria, mold, catfish and vultures
On a food web all arrows from EVERY organism would point to a decomposer

5. When organisms eat it obtains energy
When organisms eat it obtains energy. The organism uses some of that energy to move, grow, reproduce, and do other stuff
Often lost to the environment as heat
Energy pyramids show the amount of energy that actually moves from one feeding level to another
As you move up the pyramid the amount of energy available gets less.
Only 10 % of the energy moves from level to the next

6. At the top, above the first page you glued in copy this energy pyramid

8. What part of the pyramid would you label producers as?

9. producers

10. What part of the pyramid would you label First-Level Consumers as?

11. First-Level Consumers

12. Where would you put Second-Level Consumers?
Third-Level Consumers?

13. Third-Level Consumers
Second-Level Consumers
First-Level Consumers
Producers

14. Now we need organisms. Place a hawk, grass, a rabbit, and a snake into the correct part of the pyramid
Place the value 330,000 kcal into the bottom part of the pyramid
Determine how much energy moves to the next pyramid. (Hint: look at your notes to see what percentage moves from level to the next!!!)

15. Third-Level Consumers
Hawk
330 kcal
Second-Level Consumers
Snake
3,300 kcal
Rabbit
33,000 kcal
First-Level Consumers
Grass
330,000 kcal
Producers

16. As we go through the online activity you should be answering questions and/or filling out your data table
