parasitism
Dogs/fleas is an example of a Host/parasite relationship.
The relationship between dogs and their fleas is not symbiotic as the dog gains no benefit from it whatsoever. The relationship is purely parasitic.
an example would be a flea and a dog. The flea drinks the dogs blood, but does nothing beneficial for the dog.
There is no direct relationship between roses and dogs. They are two different things and do not have a specific connection or interaction with each other.
Paratism, in which the dog would be the host and the tick would be the parasite, because it depends on the dogs blood.
The relationship between a dog and a flea is called parasitism. Parasitism is a relationship between an organism and a parasite in which the parasite needs the organism to live. Without host, adult fleas can only live about two weeks. An example of a close living relationship, like fleas on dogs, is the Oculotrema Hippopotami, which is a parasite that lives in most Hippopotamus' eyes and gets rid of the algae in them. Also, many birds live near Hippos and stand on their backs for a great deal of the day to rest there while catching birds, but they also eat the bugs off of the Hippo's skin.
Fleas suck the dogs blood, and causes itch. The flea is a parasite to the dog.
It is a parasite - host relationship. The fleas as parasites living off of the dog as a host.
It's not a symbiotic relationship ! It's a parasitical relationship. In a symbiotic relationship - BOTH organisms benefit form each other. In a parasitical relationship - only ONE of the organisms benefits - usually to the detriment of the other. Fleas suck blood from dogs - which can make the dog ill. The dog gets no benefit.
So the relationship between the two is good
parasitism
It is when one organism does somthing to another organism that hurts it, such as: a mosquito biting a human. The mosquito takes blood from human and may inject disease which may harm the human. The mosquito gets food, but the human may become sick.
