The base or basal species in a food web are those species without prey and can include autotrophs or saprophytic detritivores (i.e., the community of decomposers in soil, biofilms, and periphyton). The parasite gains while the host is harmed. Community ecology is the study of the relationship of populations in an area. The interaction among organisms within or between overlapping niches can be characterized into five types of relationships: competition, predation, commensalism, mutualism and parasitism.

The parasite either feeds on the host, or, in the case of intestinal parasites, consumes some of its food. The relationships between members of different populations are termed interspecific relations. a) The competitive exclusion principle, also called Gause's Principle, states that when two species compete for exactly the same resources (thus, they occupy the same niche), one is likely to be more successful. That's just the way nature works.
