No, worms do not have a stomach--they do have a crop and a gizzard, as part of the digestive tract. The mouth of the worm connects directly to this tract, which runs the entire length of it's body.
No, worms do not have tongues. They use their muscular pharynx to push food into their digestive system.
yesType your answer here...

No. plants do not digest food, they make their own from sun-light, water, CO2, and soil minerals. Plants don't need a digestive system. Animals, in other words, do.I think plants are the only organisms that don't have a digestive system. Many species of the Protists never developed a digestive system. Some unsegmented worms that have taken up a parasitic livelihood (such as Hook Worms and tape worms) have lost what digestive they once had and absorb their nutrients directly through their skin.
Worms have a very special digestive system. Instead of having a small and large intestine, worms have only one. And it is called an intestine. They also have organs known as the crop and gizzard, which breaks down the food, since the only thing that worms do is eat. Those are the only things that worms have different than humans
yes and a very complex one at that you should google it :P
