There are several different factors that control the primary productivity of energy and biomass flow. Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured […]
(par 3. 4.2) The Flow of Energy in Ecosystems
http://www.biologie.uni-hamburg.de/b-online/e54/54c.htm The Flow of Energy in Ecosystems – Productivity, Food Chain, and Trophic Level As was explained in the last subchapter, the flow of energy is an essential feature of every ecosystem, since all living systems are open systems. They depend on a steady supply of energy in order to keep up the structural organization […]
