Why is a key helpful in the identification and classification of an organism?
Try to collect all the currently accepted meanings for the word species. Discuss with your teacher the meaning of species in the case of higher plants and animals on one hand and bacteria on the other hand.

(a) Species → Order → Phylum → Kingdom
(b) Genus → Species → Order → Kingdom
(c) Species → Genus → Order → Phylum
Define a taxon. Give some examples of taxa at different hierarchical levels.
