Detailed explanation-1: -Parasitism refers to the relationship where one organism benefits from the interaction and the other is harmed. Commensalism is when one organism benefits and the other is left unharmed, and mutualism is when both organisms benefit from the interaction.

Detailed explanation-2: -The parasite is the organism that benefits from the other. The host is the organism that is harmed by the other. Parasites are defined as organisms that live in or on another organism (host) and benefit at the host’s expense.

Detailed explanation-3: -Parasitism is the interaction between two species where only one benefits from the other organism and the other is harmed in return. The one that benefits from the other organism is called a parasite, while the organism that is being harmed is called a host.

Detailed explanation-4: -Commensalism: In commensalism, one organism benefits while the other organism neither benefits nor suffers from the interaction. For example, a spider may build a web on a plant and benefit substantially, while the plant remains unaffected.
