Detailed explanation-1: -Parasitism is the non-mutualistic form of symbiosis, occurring when one of the organisms benefits at the expense of the other. Unlike predation, parasitism does not necessarily result in direct death of the parasitized organism, and often it is imperative to the life cycle of the parasite to keep its host alive.

Detailed explanation-2: -Commensalism happens when one species lives with, on, or in another species, known as the host. The host species neither benefits nor is harmed from the relationship.

Detailed explanation-3: -If one organism benefits and the other neither benefits nor is harmed, the interaction is called commensalism. If both organisms benefit, the interaction is called mutualism. If one organism is harmed and the other benefits, the interaction is called parasitism.

Detailed explanation-4: -Parasitism is a kind of symbiosis in which one organism (referred to as the parasite) benefits at the expense of another organism (referred to as the host); the interaction may also cause harm to the host.

Detailed explanation-5: -Symbiotic relationships are the close associations formed between pairs of species. They come in a variety of forms, such as parasitism (where one species benefits and the other is harmed) and commensalism (where one species benefits and the other is neither harmed nor helped).
