In this episode, we'll revise the principles of biological classification, including the hierarchical system used to group organisms from domain to species. We'll explain binomial nomenclature and why every species is assigned a unique two-part scientific name. Finally, we'll look at how dichotomous keys are constructed and used to identify unknown organisms through a series of contrasting choices. By the end of this episode, you'll have a clear understanding of these essential syllabus concepts and be better prepared for Cambridge AICE Marine Science exam questions.
