The process of naming and grouping organisms is known as taxonomy. This naming system was started by Carolus Linnaeus. The system groups plants and animals by relationships and characteristics. Each organism is given a Latin name.
I believe the choice of Porphyry in the portrait group of tetrarchs speaks to imperial power. Portrait of the Four Tetrarchs is a porphyry sculpture group of four Roman Emperors dating from around 300 AD. The sculptural group has been fixed to a corner of the facade of St mark's Basilica in Vence, Italy since the Middle Ages.

Bacteria is important because this bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil. During assimilation, or when plants take up nitrates from the soil, bacteria aid in the process with the plants in making ammonia. Animal wastes is also a major place where bacteria thrives and produces ammonia. The process in which assimilation occurs in plants, and then bacteria converts the nitrates to ammonia is called ammonification. From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification. The nitrifying bacteria mostly present in soils, oxidize ammonia into nitrites, and from nitrites to nitrates.
Finally, the process of denitrification also has bacteria present to aid in converting nitrates back into a gaseous form of nitrogen in the atmosphere.
