Read the following statements about the 'digestive system' and identify the incorrect one(s) :
I.The human digestive system includes the alimentary canal and digestive glands.
II.Amoeba has a simple digestive system.
III.As the functions in an organism increase, the complexity of the digestive system decreases.
IV. The digestive system is the same in all organisms
III & IV
The statements III and IV are incorrect because :
III. As the function and complexity of organisms increase, obviously there would be an increase in the complexity and functionality of organs, glands and the physiology itself, of the digestive system.
IV. Likewise, as the evolutionary hierarchy increases, there would be an increase of complexity in organs and systems as well, to indicate that digestive system in organisms differ from one another based on their food habits and their structural organization
