Why are living organisms classified?
Living organisms are classified because it is nearly impossible to study all living organisms individually. Since millions of plants and animals have been identified and described, with a large number still remaining unknown, classification becomes essential to make their study manageable.
Classification is the process by which organisms are grouped into convenient categories based on some easily observable characters. This facilitates the study of kinds and diversity of organisms and helps in identifying similarities and dissimilarities among individuals of the same kind as well as of other kinds of organisms.
Additionally, such taxonomic studies are useful in agriculture, forestry, industry and for knowing our bio-resources and their diversity.
Explanation
The textbook context clearly states that since it is nearly impossible to study all living organisms, classification becomes necessary. The context emphasizes that classification facilitates the study of diversity of organisms by grouping them into convenient categories based on observable characters. The answer draws directly from the provided context without adding external information.
