It is a parasitic relationship. That means that the relationship is beneficial to the flea, but harmful to the dog.
The relationship between dogs and their fleas is not symbiotic as the dog gains no benefit from it whatsoever. The relationship is purely parasitic.
Parasitism
parasitism
There is no symbiotic relationship, fleas are parasites.
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.
I would say parasitism - host (dog) and parasite (flea).
Not really. Fleas and ticks both occasion the German shepherd, however the dog doesn't benefit from either relationship. no they don't
Fleas suck the dogs blood, and causes itch. The flea is a parasite to the dog.
they have a parasitism relationship
The flea is a parasite on the dog. So are ticks and mosquitoes. Parasites have a symbiotic relationship with their hosts, but only the parasite benefits. They get a meal but the dog can be harmed by the bite.
The relationship of a tick to a deer is parasitic, not symbiotic.
Dogs/fleas is an example of a Host/parasite relationship.
