Question

which of the below best describes the focus of the questions in the dichotomous key? observable features of fish descriptions of habitat for fish descriptions of eating behaviors of fish skeletal structures of fish

Explanation:

A dichotomous key is a tool that allows the identification of organisms based on their observable traits. It does not focus on habitat descriptions (which are about where an organism lives), eating behavior descriptions (which are about how an organism feeds), or skeletal structures (which often require dissection or more in - depth anatomical study beyond simple observation for a basic dichotomous key). Observable features are what can be seen on the outside of the fish without complex analysis.

Answer:

observable features of fish
