Answer :
A dichotomous key is a tool used in biology to identify and classify organisms based on their characteristics. Each question in a dichotomous key has two possible answers, usually presented as a pair of contrasting characteristics or traits.
How do you identify a dichotomous key?
Due to the fact that the word "dichotomous" refers to something that is divided into two halves, the dichotomous keys always offer two options based on the essential traits of the organism at each phase. The user will be able to identify the name of the creature by making the proper choice at each stage.
The user of the key must choose the answer that best matches the organism they are trying to identify, and then follow the corresponding instructions to move to the next question in the key. Through a process of elimination, the user can eventually narrow down the possible identities of the organism until they reach a definitive conclusion. So, a dichotomous key has two answers for each question.
