1. How does Energy Flow within an ecosystem?

2. Pass out Blocks

4. Producers (autotrophs)
Organisms that make their own food using the sun’s energy
(Photosynthesis)

5. Seagrass Phytoplankton
Examples: (Plants)
Seagrass

6. Primary Consumers
The 1st level of heterotrophs that get their energy by eating producers

7. Examples: (Herbivores)
Blue Tang
Green Sea Turtle
Manatee

8. Secondary Consumers
The 2nd level of heterotrophs that get their energy by eating primary consumers

9. Examples: (Carnivores)

Dolphins
Most larger fish
Most Sea turtles

10. Top Predator (tertiary consumer)

14. Questions: List 3 terms that can be used to describe:
A tree
A cow
A human
A lion
Do organisms always stay in one level? Why or why not?

15. Biomass - The total mass of living matter at each trophic level
Decreases with each level because there are less organisms and therefore less energy available.

16. The trophic pyramid has an ecological efficiency of 10% - only 10% of the energy from one level transfers to the next. 90% is lost to normal body processes (hunting, mating, etc.)
