Found inWikipedia, Jan. 5, 2010: Species (In biology, a species is a taxonomic rank (the basic rank of biological classification) or a unit at that rank; a common definition is that of a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not (normally) happen; some biologists may view species as statistical phenomena, as opposed to the traditional idea, with a species seen as a class of organisms) Organism (In biology, an organism is any living system (such as animal, plant, fungus, or micro-organism); scientific classification in biology considers organisms synonymous with life on Earth; All organisms are classified by the science of alpha taxonomy into either taxa or clades. Taxa are ranked groups of organisms, which run from the general (domain) to the specific (species))
Henderson's dictionary of biological terms, 2000 (species: in sexually reproducing organisms, a group of interbreeding individuals not normally able to interbreed with other such groups. A species is given two names in binomial nomenclature, the generic name and specific epithet ... Species can be subdivided into subspecies, geographic races, and varieties; organism: any living thing)
The American Heritage dict. of the Engl. lang., c2000 (species: 1. a. A fundamental category of taxonomic classification, ranking below a genus or subgenus and consisting of related organisms capable of interbreeding. b. An organism belonging to such a category, represented in binomial nomenclature by an uncapitalized Latin adjective or noun following a capitalized genus name; organism: 1. An individual form of life, such as a plant, animal, bacterium, protist, or fungus; a body made up of organs, organelles, or other parts that work together to carry on the various processes of life)
