Question

scientists classify organisms into groups, usually with a dichotomous key. * 5 points using a dichotomous key is like solving a puzzle, one in which you make choices about the organisms you are trying to classify. to classify this organism, you must complete the second tier of this dichotomous key. what would be the best choice for the second tier? insect or sea creature size of body six legs or eight legs two body segments or three body segments

Explanation:

The dichotomous key already shows differences in body - segment characteristics in the third tier. The most logical next - level division for organisms with exoskeletons would be based on the number of body segments as it is a major distinguishing feature. The options on the third tier are grouped by two - body segments and three - body segments for different organisms.

Answer:

Two body segments or three body segments
