Each species is classified into one of these six kingdoms: plants, animals, protists, fungi, archaebacteria and eubacteria.
A phylum is a grouping of organisms in one kingdom that have the same body plan.
Classes are a further grouping of organisms with similar traits.
Animals in the same order share further characteristics, such as being warm blooded.
The classification of family becomes more specific, with organisms sharing many physical traits.
In the genus classification, organisms are structurally related.
In a species, organisms can exchange genes and interbreed.
