Flatworms Have

Question

Flatworms have
A) Many representatives that are parasitic
B) No structure capable of gathering food actively
C) A complete digestive tract with mouth and anus
D) Only free-living representatives

Accepted Answer

Flatworms, including many parasitic species such as tapeworms and flukes, are known for their diversity with a significant number being parasitic. They do not have a complete digestive tract; instead, they have a mouth but no anus, and their food gathering is not entirely passive. Not all flatworms are parasitic; there are also free-living species.
