What is Classification
• arranging living organisms into
groups based on similarities in
structure, embryology, and DNA.
![Page 3: 1 Ecology](https://reader035.vdocument.in/reader035/viewer/2022062513/5576d919d8b42a87588b4a91/html5/thumbnails/3.jpg)
Why Classify Organisms
• Aiding the identification of species
• Shows evolutionary links
• Predicting characteristics shared by similar species
![Page 4: 1 Ecology](https://reader035.vdocument.in/reader035/viewer/2022062513/5576d919d8b42a87588b4a91/html5/thumbnails/4.jpg)
Species
• a group of organisms with similar characteristics
• can interbreed and produce fertile offspring. • DNA will also be very similar.

Binomial System
• 2 names are used to refer to each species
Genus Species Common Name
Apteryx australis Brown Kiwi
Apteryx haastii Great Spotted Kiwi
Apteryx owenii Little Spotted Kiwi

Kingdoms of Life
• Prokaryotae
• Prokaryote cells: – Unicellular– no nucleus– no organelles
![Page 7: 1 Ecology](https://reader035.vdocument.in/reader035/viewer/2022062513/5576d919d8b42a87588b4a91/html5/thumbnails/7.jpg)
Kingdoms of Life
• Protoctista
• Eukaryote cells– unicellular & simple multicellular– Nucleus– organelles
![Page 8: 1 Ecology](https://reader035.vdocument.in/reader035/viewer/2022062513/5576d919d8b42a87588b4a91/html5/thumbnails/8.jpg)
Kingdoms of Life
• Fungi
• Eukaryote cells– uni- to multicellular– Heterotrophs– mostly saprotrophs
![Page 9: 1 Ecology](https://reader035.vdocument.in/reader035/viewer/2022062513/5576d919d8b42a87588b4a91/html5/thumbnails/9.jpg)
Kingdoms of Life
• Plantae
• Eukaryote cells– Multicellular– Autotrophs– cellulose cell walls
![Page 10: 1 Ecology](https://reader035.vdocument.in/reader035/viewer/2022062513/5576d919d8b42a87588b4a91/html5/thumbnails/10.jpg)
Kingdoms of Life
• Animalia
• Eukaryote cells– multicellular– Heterotrophs– lack cell walls

Seven Levels of Classification
• Kingdom• Phylum• Class• Order• Family• Genus• Species
• Kiwis• Play• Cricket• On• Flat• Green• Surfaces
![Page 15: 1 Ecology](https://reader035.vdocument.in/reader035/viewer/2022062513/5576d919d8b42a87588b4a91/html5/thumbnails/15.jpg)
Rules
1. Write Genus with capital letter, species small
2. Write Genus and species in italics
3. In an essay, once Genus name is written, can use capital letter only
4. Use sp. If species is unknown
