| amensalism (ā-měn'sə-lĭz'əm) Pronunciation Key
A symbiotic relationship in which one organism is harmed or inhibited and the other is unaffected. Examples of amensalism include the shading out of one plant by a taller and wider one and the inhibition of one plant by the secretions of another (known as allelopathy). Compare commensalism, mutualism, parasitism. |
amensalism
association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected. There are two basic modes: competition (q.v.), in which a larger or stronger organism excludes a smaller or weaker one from living space or deprives it of food, and antibiosis, in which one organism is unaffected but the other is damaged or killed by a chemical secretion.
