Answer 2

1. sac-like digestive system

• A sac-like digestive system has a single opening. Food travels into it through that, gets digested and excreta comes out of the same opening. For example, Platyhelminthes. This is also known as a digestive cavity.

1. Tube-like digestive system

• In a tube-like digestive system there are two openings. The food enters through one, gets digested and moves out of the other one in the form of excreta, after the digestion is done. Human beings have this type of a digestive system. this is also known as a digestive tract.
