Question

------- is the taxonomical classification of living organisms into successive levels of complexity.​

Answer 1

Answer:

Within each of the three domains, we find kingdoms, the second category within taxonomic classification, followed by subsequent categories that include phylum, class, order, family, genus, and species. At each classification category, organisms become more similar because they are more closely related.

Hope it helps ☺️

Answer 2

Required answer:-

Hierarchy is the taxonomical classification of living organisms into successive levels of complexity.

There are seven levels of categories where ‘kingdom’ is the highest level and ‘species’ is the lowest level. The various categories are as follows.

• Species: A group of individual organisms with fundamental similarities is called species, for example, all mango plants are included in one species. $\:$
• Genus: It consists of a group of related species that have some common characters, for example, tiger and lion come under the same genus ‘Panthera’.
• Family: It consists of a group of related genera, for example, lion, tiger and cat are included in the same family, that is, ‘Felidae’.
• Order: A group of related families constitutes an order, for example, family ‘Canidae’ (dogs) and ‘Felidae’ (cats) come under the same order Carnivora.
• Class: A group of related orders, for example, class Mammalia includes orders Carnivora and Primata.
• Phylum: In animals, related classes are categorised into phylum, whereas in plants they are categorised into divisions, for example, phylum Chordata constitutes of mammals along with birds, reptiles, amphibians and fish.
• Kingdom: Phyla that have common characters are grouped into various kingdoms, such as plant kingdom (Plantae) or animal kingdom (Animalia).
