Taxonomy Groups (taxa) are arranged in a hierarchy that extends from the most general classification down to the most specific. Kingdom…………………Animalia Phylum…………………..Chordata Class……………………..Mammalia Order……………………..Primates Family……………………Hominidae Genus……………………Homo Species………………….sapiens King Philip Came Over From Great Spain

Autotrophs versus Heterotrophs Autotrophs: create their own nutrients through photosynthesis or chemosynthesis (plants, protists/algae, and some bacteria) Heterotrophs: Must obtain their nutrients from other organisms (animals, fungi, some algae and bacteria)

Eukaryotes versus prokaryotes Eukaryotes: complex cells with nuclei and many cell organelles (Animals, plants, fungi and protists) Prokaryotes: simple cells with no nuclear membrane and few organelles (archaea and eubacteria)

For each picture, label… Prokaryotic or eukaryotic Heterotroph or autotroph Unicellular or multicellular Name each… Animal - Fungi Plantae - Eubacteria Protist (Algae) - Archaea
