Or use the journal search engine.) Interactions between species Competition • In very broad terms, ‘competition’ is an interaction in which one organism consumes a resource that would have been available to, and might have been consumed by, another. • That is, one organism deprives another of some resource, and as a consequence the other organism grows more slowly, leaves fewer progeny, or is at greater risk of death. Classes of competition • Intra-specific – for food – for space – for mates • Inter-specific – for food – for space – NOT for mates
