Answer:
The correct order of taxonomic level from in largest to smallest (descending order) is-
Largest---Kingdom- 1st
Phylum- 2nd
Class-3rd
Order-4th
Family-5th
Genus-6th
Smallest- Species-7th
Taxonomical classification is a system for classification of organism based on their characteristic features. In this system, organisms are grouped in eight hierarchical categories or taxa mainly-kingdom, phylum, class, order, family, genus and species according to the similar features they share.
Kingdom- The largest taxon on hierarchy is a group of organisms sharing high number of similar features. Nowadays, there are 6 kingdoms: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria.
After kingdom, phylum,class,order,family,genus and species follows in descending order.
Species- The smallest taxon with group of organisms sharing less similar characters in taxonomical hierarchy and is the most specific level of classification.
Thus, the correct order in descending order is kingdom, phylum, class, order, family, genus and species.
