13. Food Chain
Food Chain: A series of organisms in which one organism obtains energy from another.
Food chains only show one specific path, one organism consuming another.
Menu

14. Food Web Food Web: A series of connected food chains.
A food web is much larger than a food chain because it contains numerous food chains within it.

16. What kind of Organism?
Autotrophs
Heterotrophs
Decomposers
Menu

17. Autotrophs
Self-feeding organisms, they are able to produce their own food using nonliving sources.
Examples: Plants,
Bacteria,
Flowers,
Moss
Menu

18. Heterotrophs
Other-feeding organisms, they must eat other organisms to survive.
Examples: Lions,
Birds,
Cows,
Dogs
Menu

19. Decomposers Organisms that consume dead or waste materials.
Examples: Fungus,
Dung Flies,
Wood Lice
