उत्तर
Amensalism is an association between two species where one species is harmed and other is unaffected.
Explanation:
Amensalism is an interspecific association where one species suffers harm while the other species remains unaffected. This means that one species is negatively impacted, for example, by the release of toxic substances, while the other species does not benefit nor get harmed in any way. This is different from other types of species interactions, where both may benefit (mutualism) or one benefits while the other is harmed (parasitism) or unaffected (commensalism).
