Food Web vs. Food Chain

Food Chain

Food Web Videos

Menu

Food ChainFood 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 WebFood 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?

Menu

Autotrophs Heterotrophs 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
