A biological key is a list of questions that can categorize the items.
A dichotomous key is a reference tool used mainly in biology. It allows the scientist to determine what an organism is by answering numerous questions that have only two possi â¦ ble answers. It neither can be a yes or a no, a true or false. Ultimately, the answers will point to a specific organism or some higher taxonomic level. Dichotomous keys can be very broad or extremely specific. To create a key, you need a working knowledgeof the differences between groups of organisms. The more specific the key, the more knowledge you need.
