There are three characteristics used in hierarchical classification of organisms.
First one is Complexity of cell structure, second one is Body Organisation and third one is Mode of Nutrition,
1. Complexity of cell structure-
it is called also type of cell—prokaryotic or eukaryotic. If talking about eukaryotic cell is membrane-bound organelles with a nucleus, the cellular process is can be carry with efficiently in isolation to other cells. In short, the organisms except the demarcated nucleus & different organelles need different biochemical pathways. which naturally create great effect on aspect of cell design., nucleated cells have capacity to participate in making a multicellular organism and have capability of take specialize functions
2.Body organisation –
is used in condition of organism is unicellular or multicellular. In a eukaryotic multicellular organism, cells comes together for create single organism to divide of labor. In this body design, all cells will not identical. instead, gather of cells will carry out specify functions. then, it makes basic distinction in body designs of organisms. Result is, an amoeba will different in body design from a fish.
3.Mode of nutrition: or autotrophic or heterotrophic.
Plants make their own food while animals depend on plants or other animals for their food. That’s why this will definitely have different body design.
