Question

In a taxonomic hierarchy, family is interpolated between _________________
A. Kingdom and Class
B. Class and Order
C. Order and Genus
D. Class and Genus

Answer 1

Hint: Different kinds of organisms known to scientists are studied from the taxonomical aspect which led to the development of some definite categories. These definite categories used by scientists or ranks in the classification of plants, animals, and other organisms are categorized into seven obligate categories.

Complete Answer:
The process of classification of living organisms is not a single step process but it consists of several steps, that is , it involves a hierarchy of steps in which each step represents a rank or category. Since the category is a part of the overall taxonomic arrangement, it is called a Taxonomic Category.
The diverse kinds of organisms are classified into seven obligate categories in which all living organisms are classified in a descending sequence starting from kingdom to species or in ascending sequence starting from species to kingdom.

The hierarchical arrangement is shown as follows:
- Kingdom: It is the highest category and first most category in the taxonomic hierarchy. It is a group of phyla or divisions, which have very less basic common characteristics.
- Phylum (for animals) or Division (for plants): It is a category higher than class. The term "Phylum" is used for animals whereas the term “division" is used for plants.
- Class: A class may be defined as a group of one or more related orders.
- Order: It is defined as a group of families that means related families are kept in the same order.
- Family: The next category that takes place after genus is family. It comprises various groups of related genera, which share less number of similarities as compared to that of genus and species.
- Genus: It is a group of commonly related species, and they possess many characters in common in comparison to species of other genera.
- Species: it is the basic unit of classification used by John Ray . It is defined as a group of proper and potentially interbreeding populations that are reproductively isolated and separated from other such groups.

As family is placed between order and genus. Our required option is C that is order and genus.

Note: Taxonomists have also made development by producing some sub- categories like subphylum or subdivision etc. in this hierarchy to make the arrangement more transparent and scientifically useful. Each category is termed as a unit of classification. It also represents rank in the taxonomic category.
