Taxonomy includes the arrangement of organisms into different taxa. Which of the following represents the correct hierarchy of various taxa of classification?
Correct answer: A. Species, genus, family, order, class, phylum
- A. Species, genus, family, order, class, phylum
- B. Order, family, class, phylum, kingdom
- C. Species, genus, family, class, order, phylum
- D. Species, genus, order, family, class, phylum
Explanation
The correct hierarchy of various taxa in biological classification is:Species, genus, family, order, class, phylumExplanation:1. Species: The fundamental unit of classification, consisting of organisms that can interbreed and produce fertile offspring.2. Genus: A group of closely related species.3. Family: A group of related genera.4. Order: A group of related families.5. Class: A group of related orders.6. Phylum: A group of related classes.This hierarchical arrangement helps organize and categorize living organisms based on their evolutionary relationships.Mnemonics, that one can use to memorize the taxonomic hierarchy, which is Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species, in that specific order are as follows:-"Dear King Philip Came Over For Good Soup" (the first letter of each word corresponds to a taxa)- Kingdom Phylum went to a Class and Ordered his Family to look for a Genius(Genus) who is a rare Species.The diagram, given below, illustrates the hierarchy.

About Classification and Taxonomy
Classification arranges organisms into groups based on shared characteristics, while taxonomy includes their identification, naming and systematic study. Coverage includes taxonomic hierarchy, binomial nomenclature, species concepts, criteria for classification and the major kingdoms or domains used to show evolutionary relationships.
