Detailed explanation-1: -Commensalism is a symbiotic relationship between two organisms where one organism is benefited from the other, whereas the other is neither harmed nor benefited. It is a biological interaction that organisms form, in the quest of food and shelter.
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: -Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed.
Detailed explanation-4: -In contrast, commensalism can be defined as an intraspecific relationship in which one species (the commensal) obtains benefits such as food, shelter, or locomotion from another species (the host) without causing adverse effects. Commensalism often occurs between a larger host and a smaller commensal.
Detailed explanation-5: -In a commensalism, two species have a long-term interaction that is beneficial to one and has no positive or negative effect on the other (+/0 interaction). For instance, many of the bacteria that inhabit our bodies seem to have a commensal relationship with us.
