所有生物系统的存在都是为了维持结构和秩序而持续输入能量的结果。在生态系统的规模上，大部分能量来自阳光，通过初级生产过程转化为生物量中有机物的能量，以及从邻近生态系统进口有机物。当然，有机物中能量的输入取决于“上游”生态系统的初级生产。因此，了解生态系统功能的一个关键方面是准确估计其初级生产力。
All biological systems exist as a result of continual inputs of energy to maintain structure and order. At the scale of the ecosystem, most of this energy comes from sunlight, which is converted into the energy of organic matter in living biomass through the process of primary production, and from imports of organic matter from adjacent ecosystems. This import of energy in organic matter is, of course, dependent upon primary production in the “upstream” ecosystem. Thus, a critical aspect of understanding the functioning of an ecosystem is an accurate estimate of its rate of primary production.
