1. Ecology Lesson 6 How does energy flow through an ecosystem? What energy roles do organisms play in an ecosystem? How much energy is available at each level of the energy pyramid?

2. Do Now Food you ate yesterday PlantAnimalOther List the 3 foods you ate yesterday in the first column. For each food, mark an x in the box if it came from a plant, animal, or other.

3. Essential Questions 1.What energy roles do organisms play in an ecosystem? 2.How does energy flow through an ecosystem? 3.How much energy is available at each level of the energy pyramid?

4. Vocabulary Producer Consumer Herbivore Carnivore Omnivore

5. Vocabulary Scavenger Decomposer Food chain Food web Energy pyramid

6. Assignment 1.Read page 42-47. 2.Complete the graphic organizers.

7. What energy roles do organisms play in an ecosystem? Use pages 42-43. Producers Consumers Decomposers

8. What energy roles do organisms play in an ecosystem? Use pages 42-43. Producers-An organism that can make its own food. -Producers are the source of all food in a ecosystem. Consumers- Feed on others -herbivores -carnivores -omnivores -scavengers DecomposersNature’s recycler Break down wastes and dead organisms and return the raw material to the ecosystem.

9. How does energy flow through an ecosystem? Use pages 44-45. Food ChainFood Web

10. How does energy flow through an ecosystem? Use pages 44-45. Food ChainFood Web -Series of events in which one organism eat another and obtains energy. -First organism is always a producer. -Second organism (first level consumer) feeds on producer. -Second level consumer feeds on first level consumer. -A food web consists of many interconnected food chains. -More realistic -Organism may play more than one role.

11. Draw your own food chain or web.
