At the end of this lesson, you will be able to
classify organisms into one of the six
kingdoms based on physical characteristics.
Overview
Lesson Title: 6 Kingdoms
Lesson Description: This lesson will
introduce the six kingdoms and will provide
descriptions and examples of each.
Rational
It is important for you to know this
information because as we move through our
study of ecology, you will begin to see how
organisms, no matter their kingdom, depend
on one another for basic needs in order to
survive.
Essential Question
How can learning about the six kingdoms
help us better understand our world?
Prior Learning
You recently learned what an organism is and the
characteristics of all living things. You will now
apply what you have already learned to gain a
better understanding of the physical
characteristics of each of the six kingdoms.

Archaebacteria
Structural organization: Unicellular, prokaryotic
How energy is obtained: Producers, consumers, or
decomposers
Examples: thermophiles, halophiles, methanogens
Other info:
1. Live in hostile places where other organisms
cannot survive – hot springs, salty, acidic
environments
2. 3 Categories – salt-, heat-, and acid-lovers
3. Some are methane producers – are anaerobic
4. Archae means “old” – oldest known organisms on
Earth
Archaebacteria
Hot Springs of Yellowstone National Park
Halobacteria
Eubacteria
Structural organization: Unicellular, prokaryotic
How energy is obtained: Producers, consumers, or
decomposers
Examples: cynobacteria, gram positive
Other info:
1. Most common – live in water, soil, inside and on
human body; can be harmful or helpful
2. Larger of 2 bacteria kingdoms
3. Grouped according the cell shape and structure
Eubacteria
E. coli
Protista
Structural organization: Most unicellular, some
multicellular, eukaryotic
How energy is obtained: Producers, consumers, or
decomposers
Examples: 3 categories:
1.
2.
3.
plant-like (algae – producers)
animal-like, (protozoans – consumers)
fungus-like (slime molds – decomposers)
Other info:
1. Evolved from bacteria about 2 billion years ago

Protista
Fungus-like - Slime Mold
Animal-like - Protoza
Plant-like – Algae
Fungi
Structural organization: Multicellular or unicellular,
eukaryotic
How energy is obtained: Heterotrophs
(decomposers) – get food from outside source
Examples: molds, mushrooms, yeast
Other info:
1. Cell wall of chitin
2. Absorb nutrients by breaking down organic
material
Fungi
Mushrooms
Yeast
Mold
Plantae
Structural organization: Multicellular, eukaryotic
How energy is obtained: Autotrophs (producers) –
make their own food using photosynthesis
Examples: trees, ferns, flowers, mosses
Other info:
1. Cell wall of cellulose
2. Usually green – contain chlorophyll
3. 2 categories: vascular, non-vascular
Plantae
Trees
Ferns
Animalia
Structural organization: Multicellular, eukaryotic
How energy is obtained: Heterotrophs (consumers)
Examples: Humans, insects, reptiles, amphibians,
worms, sponges
Other info:
1. Most can move from place to place
2. Usually green – contain chlorophyll
3. 2 categories: vertebrates, invertebrates
Animalia
•
•
•
•
Most complex multicellular organisms
Eukaryote
Most can move from place to place
2 categories:
1. Vertebrates – nervous column
Ex: reptiles, amphibians, people
2. Invertebrates – no nerve column
Ex: sponge, worms, bugs
• Consumers/Heterotrophs – herbivores,
carnivores, or omnivores

Student Practice
• You will use your notes to complete the
corresponding boxes for all six kingdoms
on the Keys to the Kingdom Activity.
