Explanation
Species are a natural population or group of natural populations of individuals that are genetically distinct and reproductively isolated with similar essential morphological traits. A species is also a genetically closed system because its members do not interbreed with members of other species. Species are the lowest or basic taxonomic category, e.g., mango (Mangifera indica), potato (Solanum tuberosum), and lion (Panthera leo). Hereindica, tuberosum, and Leo are species of the genera Mangifera, Solanum, and Pantera, respectively. All other taxonomic categories are defined and described in relation to species. For example, a genus is a group of species, and a subspecies or a variety is a part of a species. New species originate from already existing species. A species is considered a basic unit of taxonomy since, in the greater majority of cases, we do not have intraspecific names.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
