Question

Arrange the following in the ascending order of the Linnaean hierarchy.
A. Kingdom-Order-Species-Genus-Class-Family-Phylum
B. Kingdom- Family- Genus- Species- Class- Phylum-Order
C. Kingdom-Phylum-Class-Order-Family-Genus-Species
D. Species-Genus-Family-Order-Class-Phylum-Kingdom

Answer 1

Hint: Taxonomic hierarchy was first used by Linnaeus. It is the arrangement of taxonomic categories in descending order from higher to lower in biological classification. But in the question, the hierarchy is to be arranged in ascending order (lower to higher categories).

Complete answer: Taxa are the different groups or categories used in classification. Each taxon represents a category or rank in classification. The taxonomic hierarchy was given by Linnaeus. It is the arrangement of taxonomic categories from higher to lower in biological classification. It includes seven obligatory categories: Kingdom, Phylum, Class, Order, Family, Genus, Species. Species are the smallest, lowest, or basic unit of taxonomy. The genus includes a group of related species and is an aggregation of closely related species. The family has a group of related genera. Order is a group of families having few similar characters. Related orders are kept in a class and related classes are kept in a phylum. All animals belonging to different phyla are assigned to the highest category called a kingdom.
Arranging the categories in ascending order (from smaller to higher category):
      Species-Genus-Family-Order-Class-Phylum-Kingdom
If moving from lower to higher (species to the kingdom) categories, the number of common characters of animals goes on decreasing.
Therefore, the correct answer is option D.

Note: The species name is also called a binomial, i.e., a two-term name. For example, the zoological name for the human species is Homo sapiens. It is usually italicized in print or underlined when italics are not available.
