Answer 1

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.

Answer:

parasitism, relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.

Parasites may be characterized as ectoparasites—including ticks, fleas, leeches, and lice—which live on the body surface of the host and do not themselves commonly cause disease in the host; or endoparasites, which may be either intercellular (inhabiting spaces in the host’s body) or intracellular (inhabiting cells in the host’s body).
