Answer 1

A dichotomous key is the tool that we use to determine the identity of an organism, and classify it under a particular taxonomical category, such as class, family, or species. These keys use characteristics that separate species by their nature, for example, their morphology, their lengths, their habitats, and such.

In the following drawing, we can see an example of a dichotomous key.
