Question

What is a Dichotomous Key?

Answer 1

A dichotomous key is a tool used in biology to help identify unknown organisms. It consists of a series of choices between two statements or characteristics that help narrow down the possible options until the species is identified. Each choice leads to another set of two statements until the organism is correctly identified. Dichotomous keys are often used in field guides and other resources to help amateur naturalists and scientists identify plants, animals, fungi, and other living organisms.
