  • These organisms also differ in size, color, habitat, physiology, and morphology.
  • Biologists have developed certain rules and principles supplementary which are helpful in the identification, nomenclature, and classification of organisms.
  • Such rules and principles lie in Taxonomy.
  • The taxonomic studies are very helpful and useful in specific fields like forestry, industry, agriculture, and for knowing our bio-resources.
  • All discovered living organisms are being named so that they are known by the same name throughout the world.
