1. Ch. 13.3 & 13.4 Producers and Consumerspp

2. In an ecosystem energy flows:
Sun  autotrophs  heterotrophs
producers consumer

3. PRODUCERS/AUTOTROPHS
Can make their own food through photosynthesis or chemosynthesis
Provide ALL energy for the ecosystem

4. PRODUCERS/AUTOTROPHS
Therefore, ALL energy comes from the SUN!

5. CONSUMERS
get their energy by eating other living things such as plants and animals

6. CONSUMERS
get their energy by eating other living things such as plants and animals
- herbivores: eat producers (plants)

7. CONSUMERS get energy by eating other organisms
- herbivores: eat producers
- carnivores: eat other consumers

8. CONSUMERS get energy by eating other organisms
- herbivores: eat producers
- carnivores: eat other consumers
- omnivores: eat producers and consumers

9. CONSUMERS get energy by eating other organisms
- herbivores: eat producers
- carnivores: eat other consumers
- omnivores: eat producers and consumers
- detritivores: feed on “garbage” or dead organic matter

10. CONSUMERS get energy by eating other organisms
- herbivores: eat producers
- carnivores: eat other consumers
- omnivores: eat producers and consumers
- detritivores: feed on “garbage” or dead organic matter
- decomposer: break down dead organic matter into simpler molecules
 Recycle nutrients back into ecosystem
