Question

16 multiple choice 1 point the relationship between a tick and a human is: commensalism mutualism parasitism competition

Explanation:

• Commensalism: One organism benefits, the other is neither helped nor harmed. Ticks harm humans (by feeding on blood and potentially transmitting diseases), so this is not commensalism.
• Mutualism: Both organisms benefit. Ticks benefit (get food - blood) but humans are harmed (blood loss, disease risk), so not mutualism.
• Parasitism: One organism (parasite - tick) benefits at the expense of the other (host - human). Ticks feed on human blood (benefit) and can cause harm (disease, irritation), which fits parasitism.
• Competition: Organisms compete for resources (like food, space). Ticks and humans do not compete for resources in the way competition is defined in ecology.

Answer:

Parasitism
