What is the scientific process of identifying organisms and clarifying relationships between them called?

Correct answer: Taxonomy

Direct answer: A, taxonomy. Taxonomy is the scientific study and practice of identifying organisms, describing them, naming them and classifying them into an orderly system. Identification means determining what an organism is; classification places it in appropriate groups; nomenclature gives it a standard scientific name. A is correct because the question combines identification with systematic classification and relationships. B is wrong because morphology mainly studies form and external or structural features; it can provide evidence for taxonomy but is not the whole process. C is wrong because ecology studies interactions between organisms and their environment. D is wrong because evolution explains changes and relationships through descent over time, while taxonomy organizes and names organisms, often using evolutionary evidence. Memory cue: taxonomy identifies, names and classifies; ecology studies environment.
