predation parasitism mutualism commensalism
I gave my students this multiple choice question: Bass tapeworms attach to the gills and intestines of bass fish. These worms survive by taking nutrients from the bass. What type of relationship does this represent?

Only one answer is correct among these 4 choices:
- predation
- parasitism
- mutualism
- commensalism

Could you tell me which one is correct?

parasitism
