1. Bellringer/5.1 Notes

2. 5.1 Energy Flow

3. I. How Organisms Obtain Energy A.Plants make their own food. 1.Photosynthesis 1.Photosynthesis-process in which plants make their own food. Autotrophs a.Plants are also called Autotrophs 2.Heterotroph 2.Heterotroph- an organism that must feed on other organisms.

4. B.Types of heterotrophs: 1.Carnivore 1.Carnivore-eats other animals 2.Herbivore 2.Herbivore-only eats plants

5. 4.Scavenger 4.Scavenger-eats dead animals 3.Omnivore 3.Omnivore-eats both plants and animals

6. 5.Decomposer 5.Decomposer-breaks down and absorbs energy from dead organisms.

7. food chain 1.Energy flow is shown by a food chain organisms A.Energy flows through organisms in an ecosystem. II.Matter and Energy Flow 2.Energy flows from autotrophs to the heterotrophs and finally to the decomposers 3.Food chains have between 3 to 5 steps

9. 4.Energy is lost during each step of the food chain. Trophic Level 5.Each organism in a food chain represents a Trophic Level Food Web B.Several food chains connected together make up a Food Web. 1.Food webs paint a more realistic picture of how energy flows through an ecosystem.

10. Food Web

11. 1.E.P. get smaller as they get taller because there is less energy available for the next trophic level. C.Ecological Pyramid C.Ecological Pyramid-another model used to show how energy flows through an ecosystem.
