Detailed explanation-1: -Commensalism is a relationship between species in which one benefits and the other is unaffected. Humans are host to a variety of commensal bacteria in their bodies that do not harm them but rely on them for survival (e.g. bacteria that consume dead skin).

Detailed explanation-2: -commensalism, in biology, a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.

Detailed explanation-3: -Parasitism is a type of relationship where one organism benefits and the other organism is harmed in some way.

Detailed explanation-4: -Amensalism is a type of biological interaction where one species causes harm to another organism without any cost or benefits to itself. It can be seen as a form of interaction or competitive behaviour among other organisms.

Detailed explanation-5: -Amensalism is a non-symbiotic, asymmetric interaction where one species is harmed or killed by the other, and one is unaffected by the other. There are two types of amensalism, competition and antagonism (or antibiosis). Competition is where a larger or stronger organism deprives a smaller or weaker one of a resource.
