Food chain
• A ________________ showing how certain
living things depend on one another for
____________.
The flower gives energy to the caterpillar, who gives energy to the
frog, who gives energy to the snake, who gives energy to the owl!
These ARE food chains:
Grass  Cow  Human
Acorn  Squirrel  Bacteria
Plant plankton  Whale
Dead leaves  Worm  Robin 
Hawk
Tree buds  Deer  Cougar 
Bacteria
These are NOT food chains:
Sun  Daisy  Butterfly  Frog
Water  Algae  Fish  Turtle
Plankton  DDT  Fish  Eagle
Algae  Minnow  Bass  Plastic fishing
lure
• Corn  Mouse  Snake  Water

Food Chain Rule #1
Food chains only contain
____________________.
These ARE food chains:
Grass  Cow  Human
Acorn  Squirrel  Bacteria
Plant plankton  Whale
Dead leaves  Worm  Robin 
Hawk
Tree buds  Deer  Cougar 
Bacteria
These are NOT food chains:
• Cow  Grass  Human
• Squirrel Acorn
• Whale  Plant plankton
• Worm  Dead leaves  Robin  Hawk
• Deer  Tree buds  Cougar
Food Chain Rule #2
Food chains _______________
with a ________________.
These ARE food chains:
Grass  Cow  Human

These are NOT food chains:
• Grass  Cow  Human
• Acorn  Squirrel
• Plant plankton  Whale
• Dead leaves  Worm Robin  Hawk
• Tree buds  Deer  Cougar
Food Chain Rule #3
