a parasitic relationship a mutualistic relationship a predator-prey relationship a producer-consumer relationship
I gave my students this multiple choice question: Hookworms live inside the intestines of dogs. As the dog eats, the hookworms consume partially digested food. As a result of this nutrient diversion, the dog can become malnourished and weakened. Which best describes the relationship between the hookworms and the dog?

Only one answer is correct among these 4 choices:
- a parasitic relationship
- a mutualistic relationship
- a predator-prey relationship
- a producer-consumer relationship

Could you tell me which one is correct?
