Question

What kind of symbiotic relationship do fleas and dogs have?

Answer 1

Hint: Symbiotic relationship is a kind of relationship shared by two organisms of different species such that either only one or both get benefitted in terms of survival.

Complete answer:
Symbiotic relationships are of various types. Out of these, fleas and dogs share a parasitic kind of symbiosis. In this kind of relationship, one organism (in this case, fleas) lives on another (dogs) organism also called host organism, as a parasite. They keep extracting nutrients from the host body that benefits them but weakens the host body. Therefore, this kind of relationship is one way beneficial only.
Fleas are a kind of parasitic organisms that depend on dogs for nutritional needs. They are flightless insects, so they stick to their host body and suck its blood. They create a quite painful scenario for the dogs as they are always multiple in number. Fleas divide and grow on their host body by laying eggs on their host body itself that thus eventually increases their population on the host body. They are commonly spotted on street dog's bodies whereas they can be found on the bodies of birds or other mammals as well.
Dogs provide the most suitable habitat to these fleas. Also, besides providing nutrition, dogs' bodies provide them protection against other predators and environmental threats, therefore, fleas are common to be observed on dog's bodies as well. However, pet dogs (those living with humans) are also observed to have recitation of parasitic fleas on their body.

Note:
There are some home remedies that can remove fleas from a dog's body such as dish soap, herbal flea spray, baking soda, salt, lemon,etc. All these can be applied on the body of a dog going through flea attack. However,this remedy is practically applicable for pets only.
