Question

station 6: tapeworms and humans
tapeworms, or cestodes, are worms that are flattened like a tape measure. a tapeworm cannot live freely on its own - it survives within the gut (intestine) of an animal, including a human.
tapeworm eggs generally enter the human host from animals through ingested food/especially raw or undercooked meat. humans can also become infected if there is contact with animal stools or contaminated water. when an infection is passed from an animal to a human it is called zoonosis.
most people who have a tapeworm experience no symptoms and are unaware of hosting one. if signs and symptoms are present, they usually include tiredness, abdominal pain, weight loss and diarrhea.
a human who has a tapeworm will need treatment to get rid of it.

Explanation:

Tapeworms live in the gut of humans. One organism (tapeworm) benefits while the other (human) is harmed, which is parasitism. Evidence includes tapeworm eggs entering humans through food or contact with animal - related sources and symptoms like tiredness and abdominal pain in infected humans. The reasoning is that the tapeworm's survival and growth in the human gut causes negative effects on the human host.

Answer:

Organisms involved: Tapeworms and Humans
Claim: Parasitism
Evidence: Tapeworm eggs enter humans from animals via food (raw/undercooked meat) or contact with animal stools/contaminated water. Infected humans may show symptoms like tiredness, abdominal pain, weight - loss and diarrhea.
Reasoning: Tapeworms survive in human gut and cause harm to the human host.
