2 Organisms Identified, grouped, and classified More effectively study and communicate about themPlants and animals are classified or grouped together by characteristics they have in common
3 They may be characterized by The uses people make of themPhysical characteristicsOther categories used to put similar animals together
4 Classification Several ways of classifying agricultural animals Agricultural animals have been domesticated for some type of human useThese animals have been developed into breeds having distinctive characteristics and distinctive uses
5 Scientific Classification Binomial nomenclature: Giving two names in LatinSystem developed by Swedish Botonist named Linnaeus
6 Binomial Nomenclature Genus: First name, always capitalizedSpecies: Second name, always lowercaseBoth are underlined!

9 Common Names Are often confusing Different organisms can have similar or the same common nameDifferent parts of the country may have different common names for the same animal.
10 Scientific Classification Orderly and systematic approach to identificationBroad groups of animals are classified together in categories of common characteristics
11 Scientific Classification Each group is then broken down further into smaller categoriesProcess is repeated until the groups cannot be categorized into smaller groups.
12 Seven Levels of Classification Kingdom- largestPhylaClassOrderFamily
13 Seven Levels of Classification GenusSpecies- smallest
14 Kingdoms Animalia: all multicelled animals Plantae: multicellular plants that produce chlorophyll through photosynthesis
15 Kingdoms Monera: bacteria and blue-green algae Protista: paramecia and amoebaeFungi: mushrooms and other fungi
16 KingdomThe Kingdom animalia includes all animals ranging from a tiny gnat to huge whales. Because of this diversity we have to further subdivide into phyla.
17 Phyla The primary divisions of the kingdom Animalia The kingdom animalia is divided into twenty-seven phyla.
18 PhylaThe word phyla comes from the Greek word phulon meaning race or kindSeveral phyla are divided into subphylaMost agricultural animals belong to the phylum Chordata
19 Phyla Chordata is divided into subphylas Vertebrata – animals with backbones
20 Classes The phyla and subphyla are further divided into classes. Agricultural animals such as horses, cattle, goats, sheep, and pigs belong to the class Mammalia.
