My Wife and I.The relationship between fleas and a dog is most similar to the relationships between?
B) Foot Fungus and a Human





This is because as a parasite, Fleas offer no benefit to the Host (The Dog).





With the other options, it is a mutually beneficial relationship. (The bacteria fix nitrogen into the soil allowing the legumes to grow etc.)





However, Foot Fungus provides absolutely no benefit to humans so it is most similar to the relationship between fleas and dogs.
