Answer 3

because head lice eats your skin . and it heps them and does not help you .

• Parasitism is when one organism benefits from the relationship and the other orgamisn is harmed.

Head lice is an example of this, because humans are the host for the head lice. The host is the food source for the lice. So, the louse (lice) gets a food source and can reproduce so the eggs also survive off of the host and the louse, but the parasite can sometimes transmit diseases to the host.

Benefit:

The lice has a food source and shelter!

Harmed:

The human can contract diseases from the parasite. (One thing to remember, though. Is that with parasitism, the parasite does not usually kill the host. *The host is the source of shelter and food! Why would they kill the only thing keeping them alive!?)
