Q.Explain, with suitable examples of one plant and one animal, how the taxonomic hierarchy is used to classify an organism from kingdom down to species.

[!TLDR] The taxonomic hierarchy places an organism through nested ranks from Kingdom down to Species. [!ANSWER] For the mango: Kingdom Plantae → Division Angiospermae → Class Dicotyledonae → Order Sapindales → Family Anacardiaceae → Genus Mangifera → Species indica. For the domestic cat: Kingdom Animalia → Phylum Chordata → Class Mammalia → Order Carnivora → Family Felidae → Genus Felis → Species catus.

The taxonomic hierarchy classifies any organism by placing it, step by step, within a nested series of seven ranks, moving from the broadest category (Kingdom) down to the most specific (Species), with each rank grouping the rank below it on the basis of shared characters.

Applied to a plant — the mango: Kingdom Plantae (all plants); Division Angiospermae (flowering plants); Class Dicotyledonae (plants with two seed leaves); Order Sapindales; Family Anacardiaceae; Genus Mangifera; Species indica. So the full classification is Mangifera indica.

Applied to an animal — the domestic cat: Kingdom Animalia (all animals); Phylum Chordata (animals with a notochord/backbone); Class Mammalia (animals that nurse their young); Order Carnivora; Family Felidae; Genus Felis; Species catus. So the full classification is Felis catus.

In both cases, moving from Kingdom toward Species, each successive rank shares more specific characters with a smaller number of related organisms, until the species rank identifies one single, distinct kind of organism precisely. The parallel structure — despite 'Phylum' being replaced by 'Division' for plants — shows how the same seven-level hierarchy applies consistently across the whole living world. [!ANSWER] The taxonomic hierarchy places any organism through seven nested ranks — Kingdom, Phylum/Division, Class, Order, Family, Genus, Species — narrowing from the broadest group to one exact species, as shown for Mangifera indica (plant) and Felis catus (animal).

Work through all seven ranks in order for one plant and one animal example, explicitly naming each rank rather than only giving the final binomial name.

Students often jump straight to writing only the final genus+species name without showing the full intermediate hierarchy (Phylum, Class, Order, Family) that the question specifically asks to be explained.
