Question

Which of these terms is used in the classification of species?
A. Division
B. Phylum
C. Class
D. All of the above

Answer 1

The system of taxonomic hierarchy classifies the organisms in a sequence of categories in ascending or descending order. The kingdom is the highest rank provided to an organism. The lowest rank provided to an organism is called species.

Complete answer:
Taxonomic Hierarchy is a field of biology that deals with the classification and organization of organisms in taxonomic order. The term ‘taxonomy’ is a Greek word that means a division method. Taxonomy simply deals with the process of classifying living species into different categories. A taxon represents a particular group of organisms that are classified as a unit. Each of these levels that comes under the classification hierarchy is called the taxonomic category.
The classification system involves the highest rank called a kingdom and the lowest rank called species. The descending order of classification is kingdom followed by division, class, order, family, genus, and then at last species. The kingdom is divided into various subgroups or levels which are named Animalia, Plantae, Protista, Fungi, and Monera. The phylum levels become more specific and involve more filters for placing an organism in a phylum. With successive levels, the classification becomes more specific.
The classification can be explained through the example of the Indian Roses classification. Roses belong to Kingdom Plantae, phylum Magnoliophyta, Class Magnoliopsida, order Rosales, Family Rosaceae, genus Rosa, and species indica. So, all of the given terms are used in the classification of species.
Therefore, option D is the correct answer.

Note: A Greek philosopher named Aristotle first gave the concept of biological classification. He classified the organisms based on their characteristics, habitat, etc. The naming of organisms is also based on the taxonomic classification system. Each organism has a scientific name represented by its genus name followed by species name.
