A tick and a dog have this type of relationship?
Alla [95]

Answer:

Parasitism

Explanation:

First, let's define each term.

<u>Mutualism:</u> A symbiotic relationship where both organisms benefit

<u>Commensalism: </u>An association where one organism benefits, and the other is not harmed or benefited.

<u>Neutralism: </u>2 organism interact but they have no effect on each other.

<u>Parasitism: </u>A symbiotic relationship where a parasite lives in or on another organism and harms the organism.

A dog and a tick are an example of parasitism. The tick lives on the dog and drinks the dog's blood. This is the food for the tick, so the tick is benefiting by gaining a food source. The dog can be harmed if the tick is carrying a disease, such as Lyme disease.
