The Six Kingdoms
There are 6 kingdoms that all organisms can be organized into and they are…
Archaebacteria: Prokaryotic, unicellular “ancient” bacteria that have been around for 3 billion years and live in
harsh environments like hot springs and volcanoes. Examples include: methane maker, salt lover, heat lover
Eubacteria: the majority of different types of bacteria are classified as eubacteria. They can live in soil, water
and the human body. E-Coli, salmonella, MRSA and streptococcus are examples of eubacteria. Some food borne
illnesses are due to bacteria. Eubacteria reproduce asexually by a process called binary fission.
Protists: all eukaryotes that do not fit in any other group, called the “odds and ends” group. These organisms may
have characteristics of plants, animals or fungus but do not fit well in those groups so they are considered protists.

Animal-like protists: protozoa and amoeba are animal like protists. These animal like protists move in
different ways. An amoeba uses its pseudopods to move, the flagellum uses its flagella or whip-like tail to
move, and a paramecium uses its cilia to move.

Plant-like protists: algae and seaweed are plant like protists. These organisms are like plants because
they get their energy from the sun through photosynthesis.

Fungi:
Fungus-like protists: slime molds and water molds are fungus like protists .
are decomposers because they absorb nutrients from dead organisms to get energy. Examples
of fungi are molds, mildew and mushrooms.
Plant:
Producers that use sunlight to make their own food through photosynthesis. Examples: apple
tree, roses, grass
Animal:
Consumers that eat plants and other animals for food. Animals usually move and have nervous
systems.

 Prokaryotic
 unicellular
example: extreme bacteria
 Prokaryotic
 Unicellular
examples: everyday bacteria like E-Coli
 Eukaryotic
Mainly unicellular but also multicellular
examples: algae, amoeba, paramecium
 Eukaryotic
 Unicellular
 Multicellular or unicellular
 Decomposer
examples: mushroom, mold, yeast
 Eukaryotic
 Multicellular
 Make their own food/producers
Examples: trees, flowers, ferns
grass
 Eukaryotic
 Multicellular
 All move
 Consumers
 Examples: fish, worms, insects,
humans, tigers
