Transcript Food Chain Notes

Food Chain Notes
Food Chain:
A series of events in which one organism eats another
and obtains energy
Example:
Grass -> Rabbit -> Coyote -> Bacteria
 Producer: An organism that makes its own
food
 Symbol : P
 Example: Any green plant
 Herbivore or Primary Consumer: Organisms
that only eat plants
 Symbol : C1
 Example: Moose, Deer, Elk, Rabbit, Zebra
 Carnivore or Secondary Consumer:
Organism that eats other animals
 Symbol: C2
 Example: Coyote, Wolf, Shark, Lion, Snake
 Omnivore: Organisms that eat other
organisms and plants
 Example: Raccoons, Black Bear, Humans
Scavenger: Animals that feed on
the bodies of dead organisms
 Example: Turkey Vulture, Hyena
 Decomposer: Organisms that break down
wastes and dead organisms and return the
raw materials to the ecosystem
 Example: Bacteria, Fungi
 Symbol: D/S

Show Mr. Grindle when finished
Go to the corner where you think
the animal or plant belongs (SKIP
FOR NOW!!!)
 A: Herbivore (By the door)
 B: Carnivore (By the TV)
 C: Omnivore (ElK)
 D: Decomposer/Scavenger( In the back by
Spikes cage)
 E: Producer (center)

Energy Pyramid Simulation
 Run the simulation.
 Place the animals in the correct location on
the pyramid.

Answer the following questions.


1. Using numbers, how did the bottom of the
pyramid compare to the top?
2. Did any animals/plant locations surprise you?
Why or why not?
 Show Mr. Grindle when finished

Create a food Chain from the
following individuals. Check with
