Food Chain
Food Chain: A series
of organisms in which
one organism obtains
energy from another.
o Food chains only
show one specific
path, one organism
consuming another.
Menu
Food Web
Food Web: A series of
connected food chains.
o
A food web is much
larger than a food chain
because it contains
numerous food chains
within it.

What kind of Organism?
Autotrophs
Heterotrophs
Menu
Decomposers
Autotrophs
 Self-feeding
organisms, they are able to
produce their own food using nonliving
sources.
Examples: Plants,
Bacteria,
Flowers,
Moss
Menu
Heterotrophs
 Other-feeding
organisms, they must eat
other organisms to survive.
Examples: Lions,
Birds,
Cows,
Dogs
Menu
Decomposers
 Organisms
that consume dead or waste
materials.
Examples: Fungus,
Dung Flies,
Wood Lice
