The flow chart below indicates the hierarchical levels of the Linnaean classification system.

In the flow chart, the classification levels become more specific from left to right. An individual Kingdom, for example, is a more general rank, and contains more organisms, than an individual Phylum contained within that Kingdom.

Domain is another classification rank that can be used to classify organisms. Where would Domain best fit in the hierarchical chart shown above?

between Genus and Species

after Species

between Kingdom and Phylum

before Kingdom

before Kingdom
