A farmer has to get a sack of corn, a chicken,
and a fox across a river. The farmer is only able
to bring one of the above items along with him at
a time. The only problem is if he leaves the fox
alone with the chicken, the fox will eat the
chicken, and if he leaves the chicken along
the corn sack, then the chicken will eat the
corn sack. How does the farmer get all 3 items
across safely

  into orderly groups based on their similarities
• Classification is also known as taxonomy
• Taxonomists are scientists that identify name
  organisms

Benefits of Classifying

• Accurately uniformly names organisms
• Prevents misnomers such as starfish jellyfish
  that aren't really fish
• Uses same language (Latin or some Greek) for all
  names
