Answers (1) Jewels Vern. Energy is sometimes defined as capacity to do work. But work is defined as disordering energy. So energy is capacity to do disordering energy. That is a circular definition. Energy is not a physical unit. It is a philosophical concept and an accounting technique used to analyze mechanical and chemical exchanges. In nuclear physics it is defined as a wavelength of light, in biology it is a synonym for metabolism, and in public utilities they say energy when they mean connectivity. Anybody who uses the word in any other context does not know what he is talking about.

The classification levels become more specific towards the bottom. Many organisms belong to the same kingdom, fewer belong to the same phylum, and so on, with species being the most specific classification. A species is one group of genetically distinct, interbreeding organisms.The average genetic differences within a species are less than the average differences between that species and a closely related group of organisms. species is one group of genetically distinct, interbreeding organisms.
