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.
T he term species is defined as a group of organisms which interbreeds under natural circumstances, producing viable, fertile offspring, and which is reproductively isolated from other groups.This definition is known as the Biological Species Concept.hapter 4: Speciation and Phylogeny What is a species? The term species is defined as a group of organisms which interbreeds under natural circumstances, producing viable, fertile offspring, and which is reproductively isolated from other groups.
âA biological species is a group of interbreeding or potentially interbreeding organisms that can produce viable offspring.â. Advantages: This is a species concept based on a mechanism. Either individuals can or cannot produce viable offspring, although failure may be down to individuals.The issue of potential interbreeding arises when members of populations are separated but are brought into contact in a lab, or by chance mechanisms.hatâs right, definitions plural. Different areas of biology use different species concepts, depending on the organisms and data available. Each of the major species concepts is explained below, along with the advantages and disadvantages of the species concept and which areas of biology use the definition.
