In parasitism, the organism that benefits is called the parasite, and it relies on the host organism for its survival and reproduction. The host organism, on the other hand, experiences negative effects such as reduced fitness or damage to its tissues. This type of relationship is common in nature, with examples including fleas on dogs, ticks on humans, and tapeworms in the intestines of animals.Rate this question:

Leeches have been used for medicinal purposes. The leech benefits by getting blood (food) from humans. How do humans benefit from the mutualistic relationship?
- A.
The leech helps improve blood flow in the human
- B.
The leech reduces the human's chance of a bacterial infection
- C.
The leech improves the cosmetic look of the human
- D.
None of the above
Correct Answer
A. The leech helps improve blood flow in the humanExplanation
In this mutualistic relationship, humans benefit from the leech by improving blood flow. Leeches secrete a natural anticoagulant called hirudin, which prevents blood from clotting. This allows the leech to feed on the blood for a longer period of time. However, this also has a positive effect on the human host, as improved blood flow can help to alleviate conditions such as congested veins or blood clots. Therefore, the leech's presence helps to improve blood circulation in the human, making it the correct answer.Rate this question:
