Observe the skulls and teeth of the four animals. What role do the teeth play in the digestive system? Do any of the organisms have teeth that you think are used for specific functions (grinding, tearing, etc.)? How does the shape of the animals' teeth vary based on diet? Based on your observations of the skulls and teeth of each of these animals, how would you classify their diets’ (herbivorous, carnivorous, or omnivorous)?<br> | |||
Note the size of the stomach relative to the total length/size of the digestive tract in each organism. Which diet (herbivore, carnivore, or omnivore) correlates to the largest stomach relative to overall size of the digestive tract? What do your observations about the relative size of each organism's digestive organs suggest about the volume of food consumed in one feeding? Do you think each animal can eat more sporadically than others due to the size of the stomach? What does this tell you about the nutrient content of the food consumed by each organism per feeding? <br> | Note the size of the stomach relative to the total length/size of the digestive tract in each organism.
