Answer:
D. Ticks live on and drink blood from a cow.
This is an example of parasitism, where the ticks (parasite) are living off of the blood of the cow, the host animal.
Explanation:
Parasitism is a relationship between organisms. In this relationship, one organism (parasite) lives on or in another organism (host) and gains benefits from the host, causing it some harm.
Parasites are classified as ectoparasites, which live on the body surface of the host (ticks, fleas, leeches, and lice) and endoparasites, which live in the body of the host. Endoparasites are either intercellular, which live inside the host’s body (round worms, tapeworms) or intracellular, which live inside the cells in the host’s body (bacteria or viruses).
Parasites help to control dominant species and has a role in evolution by transferring genetic material between species.
