The third super-category is Domain Eukarya. This is a huge Domain that includes all eukaryotic life forms. Each organism in this Domain have eukaryotic based cells that have a true nucleus, DNA and membranous organelles. Organisms within can be Unicellular (some Protists and yeasts), Colonial (some Protists) or Multicellular (most Fungi, Plantae, and Animalia) organisms. Whereas some can be motile (ability to move around) or non-motile. Certain organisms either reproduce asexually or sexually while others do a bit of both. In order to consume food and energy, certain members of this Domain will synthesize their own (autotrophic) or hunt down and consume another living thing (heterotrophic). This Domain divides into 4 smaller sections called Kingdoms. Within each Kingdom there are 7 levels of classification. They go in the order: Kingdom, Phylum, Class, Order, Family, Genus, Species. The Domain Eukarya arose from the first prokaryotic organisms more than 1.7 billion years ago. All organisms in this Domain are prominent all over the earth, as they can be found underwater or on land, in many different biomes. 5 examples of some of the organisms found in this Domain are: Horses, Mushrooms, Diatoms, Roses and Mold.
