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.
