Which type of organism has a relationship with another organism where one benefits and the other is harmed?

(Answer) parasitism

To find the answer to your question, we can start by understanding the concept of organism relationships.

There are three main types of organism relationships: mutualism, commensalism, and parasitism. Mutualism is a relationship where both organisms benefit, commensalism is a relationship where one organism benefits and the other is unaffected, and parasitism is a relationship where one organism benefits while the other is harmed.

Now, to specifically answer your question, we can see that the type of organism relationship you are referring to, where one organism benefits and the other is harmed, is called parasitism. In parasitic relationships, the organism that benefits is known as the parasite, while the organism that is harmed is known as the host. The parasite relies on the host for resources, such as food or shelter, while the host suffers from the negative effects of the parasite's presence.

So, in summary, the type of organism relationship where one organism benefits and the other is harmed is called parasitism.

Parasitism is a type of symbiotic relationship where one organism, known as the parasite, benefits at the expense of another organism, known as the host. The parasite harms the host in some way, either by feeding on its tissues, blood, or resources, or by causing disease or other detrimental effects. Examples of parasites include ticks, fleas, tapeworms, and some bacteria and viruses that cause diseases in plants, animals, and humans.
