Parasites such as tapeworm, planarian and live fluke have digestive systems that are saclike. Their digestive tracts have one opening and they live inside a host animal.
because they are simple organism
omnivore
A more complex digestive system with specialized regions allows for efficient food processing, including mechanical breakdown, chemical digestion, and absorption of nutrients. This enables more diverse diets and enhances the organism's ability to extract energy from food.
An open digestive system is one where there is an entrance "mouth" in one end of the organism and an "exit" or anus of some sort in the other end of the organism. (think of worms or people). A closed digestive system is in something like a hydra or anemone where there is just one cavity and one opening that acts as both mouth and anus.

The organ system level is the fourth and highest level of organization in a multicellular organism. At this level, multiple organs work together to carry out specific functions, such as the circulatory system or digestive system.
