Energy GO Notes

2. All living things must have ______________ in order to maintain ______________________.
ENERGY
HOMEOSTASIS

3. Homeostasis:
Maintain equilibrium
Example?

4. #1 Energy Source:
THE SUN!

5. Autotroph Makes it’s own food Gets energy from the sun Photosynthesis
Example?
Plants

6. =
AUTOTROPHS
PRODUCERS

7. HETEROTROPH
Eat food for energy
Cannot make Energy
Example?
Animals

8. HETEROTROPHS =
CONSUMERS

9. Types of Heterotrophs

10. 1. Herbivore
-Eats Plants Ex. Deer, cows

11. 2. Carnivore
- Eats meat
Example?
Lions

12. 3. Omnivore
-Eats Both (plants and meats!)
Example-
Bear, humans

13. 4. Scavengers
Eat dead things. Examples? Buzzard

14. 5. Decomposers
Biodegrade things
Example?
Bacteria in a dumpster

15. ADD TO BOTTOM OF PAGE
Food chains and food webs are representations of the predator-prey relationships between species within an ecosystem or habitat.

16. Food Chain
A series of organisms each dependent on the next as a source of food. 

17. BrainPop!
Food Chains

18. Food Web
A network of many food chains.

19. Trophic level= ENERGY LEVEL
Only _______ % of energy goes to the next level.
The rest is either used or lost as _______. 10
5th Trophic Level- Quaternary Consumers- Eat Tertiary Consumers
Scavengers, Decomposers
#1 Source of Energy!
Tertiary Consumers-
Carnivore- Eats Carnivores (secondary consumers)
4th Trophic Level
Trophic level= ENERGY LEVEL
heat
Secondary Consumers
Carnivore- Eats herbivores (primary consumers)
3rd Trophic Level
2nd Trophic
Level
Primary Consumers-
Herbivore- eats producers
1st Trophic
Level
Autotroph- Plant, Producer
Pyramid of Energy

20. LOST
As you move up the pyramid, energy is ___________ so the amount of energy _________________.
Lost energy must be replaced by the ___________.
DECREASES
SUN
