The answer is parasitism! Becuase the lice harms the human and only the lice benifits!
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.
There is no symbiosis because there is no benefit to us. It's not a symbiotic relationship - they are parasites.
parasitism because the head lice is getting a place to they their nasty eggs and the human has to suffer..... only scrubs get lice
Sharks do not have a symbiotic relationship with the fish they eat. However, a lot of sharks do have a symbiotic relationship with remoras. This small, tubelike fish attaches itself to larger fish (including sharks) by means of a suction cup on its head. It eats external parasites off the shark. The remora gets a free meal and the shark gets rid of its parasites.
The relationship is parasitic, as the lice takes blood, but returns no benefit to the human host.
The human head weighs between 1,000 pounds to 2,000 pounds..... ask your teacher

A good example of a non-symbiotic relationship is parasitism. This is where one life form takes advantage of another without giving anything back. An example might be hair lice. They benefit from being on the human head, can move from place to place and spread to other people, reproduce, etc., but provide no benefit to humans. It should also be noted, though, that the above refers to the classical definition of symbiosis. Many experts today consider all relationships between two types of organisms to be symbiosis of some kind, but that would mean that the answer to your question would be that there aren't any, so it's probably not what you're looking for.
Head = (Pressure * specific gravity)/2.31 Head in ft Pressure in pound per in^2
The head contains the input organs (nose, mouth) through which air is supplied to the lungs through the trachea.
