To answer your question is to know the definition of a parasite: a species organism which nourishes itself at the expense of an organism of another species which it affects adversely but does not immediately destroy.
When a person has lice the skin may become irritated by the activities, particularly biting, of the lice. The degree of itching varies from person to person, and depends upon how sensitive the skin is to the lice.
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!?)
Because they're small and live on your head.
Yes lice are considered parasites.
Vs cuz!. Dhzbz ssh
The symbiotic relationship between a human head and lice is parasitism. This is because the lice get food and shelter but the head is itchy.
parasitism because the head lice is getting a place to they their nasty eggs and the human has to suffer..... only scrubs get lice
The answer is parasitism! Becuase the lice harms the human and only the lice benifits!
head lice benefits while the human is harmed.
Parasitism.
The relationship is parasitic, as the lice takes blood, but returns no benefit to the human host.
Parasitism, it is when one species benefits from the others expense.
Head lice are one of three species of lice that parasitize humans. The others are body lice and pubic lice. All three feed on blood.
No. Since the lice harm the person they live on it is parasitism.
There is no symbiosis because there is no benefit to us. It's not a symbiotic relationship - they are parasites.
If Hamsters somehow happen to get Head Lice the Lice will not live
