Give terms corresponding to the following definitions. The use of the hierarchical classification system


The use of the hierarchical classification system

Order defined classify features are sorted living reproduce share capable of classifying kingdom to identify Classification to sort offspring species scientists to breed breeding

CLASSIFICATION helps us to impose order and a general plan on the diversity of …………… things. Scientists have always tried to organize and …………… the objects, including living organisms, around them. …………… can be defined as grouping organisms according to their structural similarities. This means that organisms that share similar …………… are placed in one group. These groups are arranged from the largest group of organisms to the smallest group of organisms.

The groups, from largest to smallest, are arranged as follows:

……………, phylum, class, …………… , family, genus and …………... . The species is the smallest group of organisms. As you go through the classification hierarchy, you will see that …………… have used broader features to put organisms into kingdoms, which are the largest groups of organisms. When you move down towards the species, which are the smallest groups of organisms,

features are becoming specific. In other words, two organisms that belong to the same species …………… more features than those in the same kingdom but in different species.

A species can be …………… as a group of organisms with similar features, and these organisms are …………… breeding and produce fertile …………… . You are probably aware of the fact that horses and donkeys belong to the same kingdom, phylum, class, order, family as well as genus but they are from different species. Therefore, if a donkey and the horse happen …………… , they produce an offspring called a mule. The mule is infertile, meaning that it cannot …………… offspring because it is a product of organisms of different species.

Classification hierarchy has many uses. First, it helps scientists …………… organisms in order. Second, it helps them …………… new organisms by finding out which group they fit. Third, it is easier to study organisms when they …………… in groups.
