%A Mr. Atanu Bikash Chatterjee %T Interactions of Self-organizing Systems in Nature %X Nature essentially consists of complex systems. The paper presents a conceptual framework to understand how complex systems interact with each other in nature. All natural systems are thermodynamically open and physically adaptive. The process of adaptation and continual self-organization cause these systems to interact continuously with the environment and compete against such similar systems for limited resources. %D 2011 %K complex systems, complexity, information, self-organization, network, hierarchy, natural process, human mind, cognitive process %L cogprints7766
