Question

how taxonomy and hierarchy nvolved in the animal kingdom?

Answer 1

The sequence of taxa in the animal kingdom is: kingdom, phylum, class, order, family, genus and species.
Therefore, the correct hierarchical arrangement of taxonomic categories in ascending order is:
Species → Genus → Family → Order → Class → Phylum → Kingdom
(i) Phylum:
Phylum is second highest unit of classification after Kingdom. It includes one or more related classes of animals. In plants, instead of phylum, the term ‘division’ is used.
(ii) Class:
Class is a taxonomic group consisting of one or more related orders. For example, the class, Mammalia, includes many orders like Primata (Man), Carnivora (Lim, tiger) etc.
(iii) Order:
Order is a taxonomic group containing one or more families. For example, the order, carnivora, includes many families.
(iv) Family:
Family is a taxonomic group containing one or more related genera e.g., Family hominidae contains apes, monkeys and man. In plants, families are categorized on the basis of vegetative and reproductive features.
(v) Genus:
Genus is a taxonomic group including closely related species. For example, the genus, Solanum, includes many species such as nigrum, melongena, tuberosum, etc.

Answer:

There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. In addition, domain (proposed by Carl Woese) is now widely used as a fundamental rank, although it is not mentioned in any of the nomenclature codes, and is a synonym for dominion (lat.
