The other form of competition is intraspecific competition, which involves organisms of the same species. If a tree species in a dense forest grows taller than surround...

(from the article `Singing a Different Tune`) The life forms in tropical forest ecosystems, as in all ecosystems, compete for the resources available. Members of different species may compete for ...
