Why do scientists classify living things?

• It helps scientists trap species to study
• It is easier to study organisms when grouped 
• It is a good way to keep organisms calm
• It is helpful when dissecting an organism

An early classification system had two groups: Plants and Animals. What is wrong with that system?

• It is too specific
• It is too narrow minded
• It is too broad
• It is too fancy 

What statement would NOT be good for a dichotomous key?

• The organism has 1 dorsal fin
• The organism is ugly
• The organism has leaves in groups of three
• The organism has 6 legs

The correct order of classification from the BROADEST group to the most narrow is:

• Species, Genus, Family, Order, Class, Phylum, Kingdom
• Kingdom, Phylum, Class, Family, Order, Genus, Species
• Kingdom, Family, Order, Phylum, Class, Genus, Species
• Kingdom, Phylum, Class, Order, Family, Genus, Species

How do scientists organize living things?

• by looks
• by shared characteristics
• by size
• by differences
