The particular arrangement of elements and

Biological classification Biological classification is the arrangement of organisms into categories that express their PHYLOGENY, or line of descent, based on information such as structure, development, biochemical or physiological functions, and evolutionary history of organisms. The purpose of such a classification is to provide a clear and practical way to organize and communicate information about organisms. Classification can show relationships between different ancient and modern groups, indicate

to have affect on a humans body, but parasites have a greater increase in harming a human being rather than a bacteria.
