Question

What are the seven levels of classification for a dog?

Answer 1

Taxonomy (that apparently means "arrangement law") is the study of characterizing organisms in order to create globally categorization systems that group every organism into greater encompassing sections. A hierarchical system is one that organizes things from considerably larger to smaller, more precise groups.

Complete answer:
Scientists organize organisms into three big groupings termed domains after the fundamental origin of all life: Bacteria, Archaea, and Eukarya. Under every domain, there is a subsection known as a kingdom. The following groups of increasing specialization after kingdoms are phylum, class, order, family, genus, and species. Within scientific categorization, groups are organized in order of ascending intricacy. The seven levels of classification for a dog are as follows:
Kingdom—Animalia (One of the most distinguishing features of this kingdom is the lack of a cell wall)
Phylum—Chordata (The occurrence of a notochord characterizes chordates)
Class—Mammalia (This class is characterized by the ability of the organisms to give birth to young ones, the presence of mammary glands etc.)
Order—Carnivora (Carnivora represents the eating habit of the organism, in this case, dog is a carnivore meaning flesh eating animal)
Family—Canidae (It represents the dog family)
Genus — Canis
Species— familiaris

Note:
Dogs occupy a domain (Eukarya) with organisms with the greatest genetic variation, including plants and butterflies. The animals are more likely to be related at each sublevel, therefore they appear more comparable. Scientists used to classify animals based on their morphological traits, but as DNA technology advanced, more accurate phylogenetic analysis based on genetic resemblance were discovered.
