Taxonomic Levels
Organisms can be classified animals beyond just genus and species.
There are 8 levels of classification (taxa):
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
(the "domain" taxon
is somewhat new and
doesn't appear in all
texts)

3. Taxonomic Levels
These levels go from broad to specific.

4. Classification System
Where you live, from broad to specific:
- The Universe
- The Milky Way Galaxy
- Our Solar System
- Earth
- North America
- Canada
- Ontario
- Toronto
- Your address

Taxonomic Levels
Dogs and wolves are of the same species and are often able to
produce fertile offspring. However, since they are also still very
different, scientists have created a subspecies for dogs: familiaris.
Thus, the dog's full name is Canis lupus familiaris

If you had to separate all life on Earth into 6 major categories,
how would you do it?

29. Review - Before We Go Further:
What do these terms mean?
Organic (biology definition)
- Living or once-living matter.
Autotroph
- Makes its own food from inorganic sources.
Heterotroph
- Eats other organic matter.
Eukaryote
- Cells have a nucleus and other membranous organelles.
Prokaryote
- Cells have no nucleus and no membranous organelles.
