1. DRAW ON NTBK 18 UNDER KQ’S  DIAGRAM OF PRODUCERS/CONSUMERS/ AND DECOMPOSERS  CPO PAGE: 87  TITLE IT “ENERGY FLOW/NUTRIENT CYCLE”

2. SET UP NOTEBOOK PP 20-21  NEXT 2 BLANK PAGES.  COPY KQ FROM BOARD  TITLE: ENERGY PYRAMID AND TYPES OF CONSUMERS

3. THE ENERGY PYRAMID AND TYPES OF CONSUMERS Yum- what shall I eat?

4. CONSUMER CLASSIFICATION  4 different types based on what they eat  They each start with:  H-  C-  O-  S-

5. HERBIVORES  eat only plants  Examples?

7. CARNIVORES  – Eat only animals  Meat eaters  Examples?

9. OMNIVORES  eat both plants and animals  Examples?

11. SCAVENGERS  carnivore that feeds on dead organisms  Examples?

13. Energy Pyramid  Diagram -shows amount of energy (E) moving from 1 feeding level to next  Most energy is available at the producer level of the pyramid- BOTTOM  As- move up pyramid- each level has less energy available than the level below  Only 10% of energy is transferred up the levels  What is an energy pyramid?

16. PRIMARY CONSUMERS  On the Energy Pyramid  First level of consumers  Plant eaters- herbivores  Primary means first  Toward the bottom (right above the producers)

17. SECONDARY CONSUMERS  On the energy pyramid  Carnivores or omnivores  Right above primary consumers  Middle level  Less energy than lower levels

18. TERTIARY CONSUMERS  On the Energy Pyramid  third level consumer (sometimes top level)  Eats a variety of animals for food  Often is a predator  LEAST amount of energy available at this level  (quarternary consumers- 4 th level- is the absolute top level)

19. After the Quiz  Turn it over and leave it on your desk please.  Copy the Energy Pyramid from the board onto page 20 UNDER THE KQ’s. Add color if you want.  Open Holt to Chp 18, sections 1 & 2 and answer the review questions on page 437 and 443- ANSWERS ONLY- YOU CAN DO THIS ON YOUR OWN PAPER.

20. Draw an Energy Pyramid  Be sure to include the levels  Include the energy amounts at each level  Use the COACH on page 29- draw it onto page 20 under the KQ.  We will add more to it from the CPO text.
