Answer 2

Biological scientists estimate that collectively the earth’s 5 to 40 million species of organisms (depending on the estimate you choose to believe) make up a total of some two trillion tons of living matter, or biomass.  The plants comprise well over 90 percent of the biomass.  The animals, the focus of this article, comprise only a small percentage of the biomass, but they account for the majority of species. 


In accordance with the Linnaeus method, scientists classify the animals, as they do the plants, on the basis of shared physical characteristics.  They place them in a hierarchy of groupings, beginning with the kingdom animalia and proceeding through phyla, classes, orders, families, genera and species.  The animal kingdom, similar to the plant kingdom, comprises groups of phyla; a phylum (singular for phyla) includes groups of classes; a class, groups of orders; an order, groups of families; a family, groups of genera; and a genus (singular of genera), groups of species.  As established by Linnaeus, the scientists call an animal species, as they do a plant species, by the name of the genus, capitalized, and the species, uncapitalized.  So far, the scientists have classified and named something over a million animal species.  Without doubt, they have millions more to go.
