Eugene Odum, one of the founders of the science of ecology, stated:"Any unit that includes all of the organisms (ie: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (ie: exchange of materials between living and nonliving parts) within the system is an ecosystem."

一位生态科学的奠基人，说过：&任何单位，它包括某一地区内所有的生物体，这些生物体同自然环境相互作用引起能量的流动，从而生成营养结构、生物多样性和物质循环（如：有生命体和无生命体之间的物质转化），这样的单位就是生态系统。&
