Scientists classify organisms to ____
A
Count the organisms quicker
B
Catch the organisms in the wild
C
Train the organisms to behave
D
See how organisms are alike and different from each other
Explanation: 

Detailed explanation-1: -Taxonomy is the scientific method of classifying and naming living organisms by grouping them by shared traits or characteristics. This includes morphological (structural) characteristics, the genetic information of the organism, and evolutionary relationships with other species.

Detailed explanation-2: -Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related. In other words, they are descendants of a common ancestor in the past.

Detailed explanation-3: -This system of classification is called taxonomy. Scientists classify living things at eight different levels: domain, kingdom, phylum, class, order, family, genus, and species. In order to do this, they look at characteristics, such as their appearance, reproduction, and movement, to name a few.

Detailed explanation-4: -Scientists use taxonomy for organism classification to improve the understanding of the evolutionary relationship between different organisms. By grouping organisms that are similar on an evolutionary level, we can have basic knowledge about a group of organisms that can help when studying the organism later.
