Classification and Species Interactions

2. Carolus Linnaeus The “Father of Modern Taxonomy”
Established methods for classifying and naming organisms that are still used
BINOMIAL NOMENCLATURE
Two name names

4. Hierarchical Classification
It starts very broad and gets more specific
7 hierarchies in our system:
Kingdom Very broad
Phylum (Division)
Class
Order
Family
Genus
Species Very specific
Explain that kingdoms are the broadest classification and that species is the most specific. Scientists have divided all organisms into smaller and smaller groups until they have only 1 type of organism (a species). A phylum is called a division in the plant kingdom.

5. Taxonomy Kingdom: Animalia Phylum: Chordata Class: Mammalia
Order: Carnivora
Family: Urisidae
Genus: Ursus
Species: Americanus

6. The 6 Kingdoms
Kingdoms are the largest division-all organisms are in one of the 6 kingdoms
Animals
Plants
Fungi
Protists
Eubacteria
Archaebacteria
Every organism that has been discovered on earth is put into one of the six kingdoms. What kingdom an organism is classified in depends on the number and type of cells (multicellular or unicellular, eukaryotic vs. prokaryotic), whether or not they move, and how they get their food (photosynthesis or eating other organims).

7. Food Webs and Trophic Labels
A food chain represents a succession of organisms that eat another organism and are, in turn, eaten themselves.

8. Producers- autotrophs- plants Consumers- heterotrophs- animals
Omnivores: meat and plants
Herbivores: plants
Carnivores: meat
Decomposers: fungi & bacteria

10. Plants All plants are multicellular All plants are eukaryotic
All plants are autotrophic

11. Animals All animals are eukaryotic All animals are multicellular
All animals are heterotrophic

12. Species name Based on a system of binomial nomenclature
The Latin version of the genus and species of an organism
Members of a species must be able to successfully reproduce and have fertile offspring

13. Dichotomous keys What is a dichotomous key?
A step-by-step guide to identify an organism
Each step gives a choice of two descriptions.
The descriptions have to be opposites
Ex. Leaves round vs. leaves not round
