State the taxonomic hierarchy. Explain how each kingdom is divided into smaller groups?

Difficulty: Medium

Taxonomic hierarchy:

The groups into which organisms are classified are known as taxonomic categories or taxa (singular “taxon”) and these taxa form a ladder called taxonomic hierarchy. All the organisms are divided into five kingdoms:

The base for Establishing five Kingdoms:

Based on similarities, each kingdom is further divided into smaller groups in the following way:

  1. Phylum (Division: for plants and fungi):

A phylum is a group of related classes.

  1. Class: A class is a group of related orders.
  2. Order: A order is a group of related families.
  3. Family: A family is a group of related genera.
  4. Genus: A genus is a group of related species.
  5. Species: A species consists of similar organisms.

Note: Each category (taxon) is more than one below it and has emergent properties. Member of its lower taxon resembles one another more than do the members of the higher taxon.
