Question

During science class, students were instructed to develop a dichotomous key (a tool that allows the user to determine the identity of items in the natural world) in order to classify organisms into one of the six kingdoms of life. Ms. King, their teacher, provided them with this diagram. According to the diagram, the BEST way to separate all living things into two main groups would be to consider A) method of reproduction. B) consumer versus producer. C) cell type, prokaryotic versus eukaryotic. D) organization, unicellular versus multicellular.

Answer 1

The answer to this question would be: C) cell type, prokaryotic versus eukaryotic. 

In six-kingdom classification, the cell type would be same for each kingdom. A kingdom should only have either prokaryotic or eukaryotic
 
A different method of reproduction needs an advanced organ and not all kingdom have it. Consumer/producer or unicellular/multicellular classification cant differentiate between the kingdom since one kingdom can have a member with those traits.

Answer 2

Answer to this question: cell type, prokaryotic versus eukaryotic.
