What skull belongs to an omnivore, herbivore, carnivore?

• These teeth help them with ...
• Share: Talk about given answers during plenary session.

                       herbivore             omnivore             carnivore

Length of the intestinal tract

   

        Skull

        Teeth

long                     medium                short

ridged molars                 knobbly molars                 cutting molars

Plants are difficult to digest (mainly because of the cell walls), a long intestinal tract makes sure this can happen

Meat is easy to digest, a short intestinal tract is enough

The ridges help break the plant cells apart.

These teeth move over each other, they make grinding motions 

These teeth work like scissors

When eating they move next to each other, cutting the meat 

These words I'll add to my PIF
