Abstract: Competition and synergia are the two kinds of appearance behaviors widely existed in the individuals and populations in nature.A lot of experiments and researches revealed that competition is in favor of the evolution of morphological and physiological adaptation characters and life-historical strategies to a certain extent,and there is a real evolutionary process driven by competition in communities and ecosystems,while synergia can conduce to the existence and reproduction of organisms with the lowest cost of investment.According to the stability and diversity of ecosystems,competition and synergia can supplement and transform each other under certain conditions.Synergia can promote the efficiency of energy transform among all systematic components,strengthen the capability of self-organization,and maintain the order and diversity of ecosystems,which drives the biological evolution more prevalently and significantly.
