Answer 1

In biology, a dichotomous key helps to identify and classify organisms based on similar features and structures

What is a dichotomous key?

A dichotomous key is a tool used in biology to identify organisms based on similarities in their structure and function.

Organisms with similarities in their structure and function will be placed under the same category and any difference will be used to separate them.

For example in the dichotomous key for Shark, the features:

• Fish with long tubelike body will identify sharks
• Fish with body shape not tubelike will be used to separate fishes that are not shark.

Therefore, a dichotomous key helps to classify organisms based on similar features and structures.
