1. Identify the
characteristics that you
think are the most
useful for grouping the
organisms into
separate groups.
2. Classify the organisms
using a five level
system of
classification. Level 1
should include all the
organisms and Level 5
should be specific
enough to include only
one organism (you will
need 6 Level 5
classifications).
