1. Energy Flow In Ecosystems
Ch. 5 sec. 1

2. Ultimate source of Energy
Sun
Plants use sun and animals rely on plants

3. Producer An organism that makes its own food also known as autotrophs
Photosynthesis

4. Consumer
Organisms that get their energy by eating other organisms also known as heterotrophs
Cellular respiration

5. What eats what
Herbivores = plant eaters

6. Carnivores
Meat-eaters

7. Omnivores
Eat both plants and animals

8. Decomposers Break down dead organisms causing them to rot or decompose
Very important to life cycles

9. Respiration
Cellular Respiration = breaking down food to produce energy

10. Food Chain
A sequence in which energy is transferred from one organism to the next

11. Primary Producer Autotrophs or organisms that make their own food
Photosynthetic
Chemosynthetic

12. Primary Consumer
Herbivores or organisms that eat autotrophs

13. Secondary Consumer Animals that eat the herbivores (predators)
Carnivores or Omnivores

14. Tertiary Consumer Animals that consume the secondary consumers
(top predator or no natural enemies)

16. Food Web
Many of the feeding relationships in an ecosystem

17. Trophic Levels
Each step in the transfer of energy through an ecosystem
Only 10% of energy is actually transferred
