You are correct, there are only three worm phyla. So the key to the question was that your worm is segmented. All segmented worms belong to Phylum Annelida.
No, roundworms have a one-way digestive system. It's food goes in through the mouth, and out through the anus, which makes it much more efficient than a two-way digestion.

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
