•Grab both sheets off center stools.
•Please have a seat and take some time to look over the
notes worksheet. Look at the diagrams, and take a
close look at the vocabulary words. If you can use
prior knowledge to place any of the vocabulary words

 Food Chain = Flow of
energy through
organisms organized by
trophic levels.
 Trophic Level =
Position on a food chain
based on how an
organism gets energy.
 Food Web = Complex
interactions represented
by arrows. Shows several
intertwined food chains.
 Producers
 Consumers
 Carnivore
 Scavenger
 Predator
 Herbivore
 Omnivore
 Parasite
 Organisms that produce their own food (autotrophs)

 Put your name at the top of your sticky note.
 On your sticky note…
 Draw a food chain pyramid, explaining each level to the
best of your ability. Please give an example of an
organisms in each level.
 Also, what can you tell me about the transfer of energy
between each trophic level?
 When the bell rings, hand in your paperwork and
place your sticky note on the door as you leave the
room.
 Have a nice day!!!
