they have a parasitism relationship
parasitism
There is no symbiotic relationship, fleas are parasites.
It is a parasitic relationship. That means that the relationship is beneficial to the flea, but harmful to the dog.
parasitism
I would say parasitism - host (dog) and parasite (flea).
It would never be a symbiotic relationship... the relationship would be parasitic (the flea benefiting from the blood and the moose being harmed from the taking of its blood). - Actually parasitism is a type of symbiotic relationship. any close relationship between two organisms is a symbiotic relationship no matter the conditions of said relationship
There is no symbiosis between a flea and a dog. The flea is a blood eating parasite on the dog. There is benefit to the flea but not to the dog so there is no symbiosis.
The relationship between dogs and their fleas is not symbiotic as the dog gains no benefit from it whatsoever. The relationship is purely parasitic.
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.
Parasitism
parasitism Is Where Onee Organism Benefits and The Other one Is Eitherr Harmed Or Not Benefited .
