  five pieces?
• Why dont tapeworms need muscles?
• What is commensalism and what organsim uses it?

25
Short Answer

• Why do worms that live in the intestines need a
  thick outer skin? To keep from being digested in
  intestines/stomach
• How do earthworms help the environment? Castings
  fertilize, loosen soil, dig channels for water
  and air to flow, food chain
• How are porifera different from other organsims?
  No organs, tissues, or symmetry
• What happens to a planarian when it is cut into
  five pieces? It regenerates into five worms
• Why dont tapeworms need muscles? they dont
  move much just hang from organs and eat
• What is commensalism and what organsim uses it?
  One organism benefits and the other isnt
  affected the anemone and the clownfish
