Which method is used to identify each organism?

Answer: A dichotomous key is a common tool used by biologists and other naturalists to categorize an unknown organism. This “key” is a series of questions or statements asking about a specific characteristic of the organism.

What is the method that is used to classify and identify organisms?


The method of organism classification is named as Taxonomy [16]. Taxonomy uses a dichotomous key for organism identification.

What are reliable ways to classify organisms?

The science of classifying living things is called taxonomy. Linnaeus introduced the classification system that forms the basis of modern classification. Taxa in the Linnaean system include the kingdom phylum class order family genus and species. Linnaeus also developed binomial nomenclature for naming species.

Why are organisms classified?
