Question

Which of the following is an example of a host-parasite relationship? 

A. A vine getting support from a bigger plant  

B. A tick living on a cat  

C. A rhino living in the same area with an elephant

Answer 1

A host-parasite relationship is a type of symbiotic relationship in which one organism, known as the parasite, benefits at the expense of another organism, known as the host. The parasite relies on the host for resources and can harm or negatively affect the host in the process. One example of a host-parasite relationship is:

Ticks on a dog: Ticks are parasites that feed on the blood of animals, including dogs. When ticks infest a dog, they attach themselves to the dog's skin and feed on its blood. Ticks can transmit diseases to the dog, such as Lyme disease, through their bites. In this relationship, the dog serves as the host, providing the ticks with a source of nourishment, while the ticks harm the dog and obtain the resources they need to survive.

Note that there are numerous other examples of host-parasite relationships in nature, involving various organisms such as fleas on mammals, lice on humans, or tapeworms in the intestines of animals.

Answer 2

A tick feeding on a dog's blood is an example of a host-parasite relationship, where the tick is the parasite and the dog is the host. The tick requires the dog's blood to survive, while the dog suffers from the direct harm caused by the tick's bites. This relationship is common in nature, where parasites often feed on larger host organisms to gain nutrients or other benefits.

Answer 3

B. A tick living on a cat is an example of a host-parasite relationship. In this relationship, the tick is the parasite, as it feeds off the cat and does not provide any benefit to the cat in return.
