Objective
Identify, trace & evaluate the source, flow and efficiency of energy through interdependent organisms using food chains & webs.
Believe deep down in your heart that you’re destined to do great things.
- Joe Paterno

2. Where do you get your energy?

8. I. Producers & Consumers
A. Autotrophs
1. Producers that make their own food
2. Photosynthesis or Chemosynthesis
B. Heterotrophs
1. Consumers that obtain food from other organisms
How?
Who are they dependent upon for energy?

9. II. Heterotrophs / Consumers
A. Herbivores - ? (Define & Give an Example) B. Omnivores - ? (Define & Give an Example) C. Carnivores - ? (Define & Give an Example) D. Detritivores - ? (Define & Give an Example) E. Decomposers - ? (Define & Give an Example)

11. III. Food Chain A. Models linear feeding relationship
1. Energy flows through ecosystem in one direction
B. Trophic levels
Each step in the food chain (This can vary depending upon community)
Primary Producers
Primary Consumers
Secondary Consumers
Tertiary Consumers
Quaternary Consumers

12. IV. Food Web
Shows more complex/realistic feeding relationships in an ecosystem.
Trophic Levels still exist
Tertiary Consumers
Secondary Consumers
Primary Consumers
Primary Producers

13. How is Biomass expressed?
V. Ecological Pyramids
Model of energy & matter (3 Types)
1. Energy Pyramids
2. Biomass Pyramids
3. Pyramid of Numbers
KEY CONCEPT? Page 72
How is Biomass expressed?

14. Ecological Pyramids IAN p 50
Divide your notebook page into 3 triangular shapes.
Label & Create the 3 types of Ecological Pyramids using your own examples.
YOUR PYRAMIDS MUST INCLUDE:
At least 4 trophic levels w/ labels
Specific labels for each pyramid
Colorful illustrations
REFERENCE Pages in your textbook.
Energy Pyramid
Biomass Pyramid
Pyramid of Numbers
