parasitism
This term describes a one-sided relationship where one entity thrives at the direct expense of another. In biological sciences, it refers to a specific symbiotic interaction characterized by a host and a parasite, often involving complex evolutionary adaptations to evade the host's immune system.
When applied to social or economic contexts, the word carries a strong negative connotation of laziness or exploitation. It suggests a predatory lack of reciprocity, where the dependent party is viewed as a burden rather than a legitimate beneficiary of support.
