Scientists classify organisms into groups, usually with a dichotomous key. 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? A) size of body B) insect or sea creature C) six legs or eight legs D) two body segments or three body segments
the answer is C six legs or eight legs
