When multiple organisms seek the same limited resource. Subtle and indirect, involving the consequences of one organism"s ability to match/outdo others in procuring resources. Members of the same species (intraspecific competition); population level phenomenon. Fundamental niche- the full niche of a species (may exploit resources) Realized niche- the portion of the fundamental niche that is fully realized (used) by a species. Negative effect on other participants because each takes resources the others could have used. Predation- process by which individuals of one species (predator) hunt, capture, kill, and consumer individuals of another species (prey) Has evolutionary ramifications; individual predators that are more adept at capturing prey will likely live longer, healthier lives and be better able to provide for their offspring than will less adept individuals. Parasitism- relationship in which one organism (parasite) depends on another (the host) for nourishment or some other benefit while doing the host no harm.
