What term describes a symbiotic relationship between two different species in which one organism benefits at the direct expense or harm of the other?

Explanation

Parasitism is a type of symbiotic relationship between two different species in which one organism, called the parasite, benefits, often by obtaining nutrients or shelter, at the direct expense or harm of the other organism, called the host. Common examples of parasites include tapeworms living within an animal’s digestive system or fleas living on an animal’s skin, both of which draw resources from their host while providing no benefit in return. This type of relationship is distinct from mutualism, in which both participating species benefit, and commensalism, in which one species benefits while the other is largely unaffected.
