Quizplus · Accepted Answer

In parasitism, one species (the parasite) benefits by exploiting and harming another species (the host). The host is negatively impacted and may suffer from decreased fitness as a result of the relationship. commensalism is a one-way relationship in which one species benefits while the other is neither helped nor harmed. Mutualism and competition are two-way relationships in which both species interact and can either benefit (mutualism) or be harmed (competition) by each other. Succession refers to the gradual change in the species composition of a community over time.
