Taxonomy The science of describing, naming, and classifying organisms
Heterotroph Organism that cannot make its own food (consumer)
Dichotomous Key An aid that is used to identify organisms; consists of a series of answers to questions (Taxonomic Key)

Kingdom Eubacteria unicellular, prokaryote, autotroph or heterotroph
Kingdom Protista most unicellular with few that are multicellular, eukaryotes, autotrophs or heterotrophs
Kingdom Fungi mostly multicellular with few that are unicellular, eukaryotes with cell walls, heterotrophs
Kingdom Plantae multicellular, eukaryotes, autotrophs, cell walls
Kingdom Animalia multicellular, eukaryotesheterotrophs, specialized sense organs
Examples of protists ameba, seaweed, euglenga, paramecium
