1. Energy in Ecosystems

2. Food is Energy!

3. Energy in ecosystems starts with the Sun

4. Food Chains

5. Producers Produce means “to make”
Producers are the food makers – plants!

6. Consumers Consumer means “to eat”
Consumers are the food eaters – animals!
Primary consumers = “1st eaters” = eat plants
Secondary consumers = “2nd eaters” = eat plant eaters
Tertiary consumers = “3rd eaters” = eat meat eaters

7. Types of Consumers Herbivore – eats plants Carnivore – eats meat
Omnivore – eats both plants and meat
Scavenger – eats dead organisms

8. Decomposers Decomposers break apart dead things
Return important nutrients back to the soil (recycling)

9. Food Webs

10. Food Webs
Show ALL possible food chains in the ecosystem

13. Food Webs (Explain how food webs work)
(Explain what would happen if you did not have enough rabbits, or if you had too many snakes)

14. Energy Pyramids

15. Energy Pyramid Shows energy lost, as you move up each level
90% lost at each level (100%, 10%, 1%, 0.1%)
More organisms at the bottom, less at the top

16. Energy Pyramid (Explain how the energy pyramid shows energy loss)
(Explain why there are more producers at the bottom, and less consumers at the top)
