(par 3. 5 ) Energy Flow in an Ecosystem
Energy Flow in an Ecosystem http://www.biologydiscussion.com/ecosystem/energy-flow-in-an-ecosystem-with-diagram/6740 Energy has been defined as the capacity to do work. Energy exists in two forms potential and kinetic. Potential energy is the energy at rest {i.e., stored energy) capable of performing work. Kinetic energy is the energy of motion (free energy). It results in work performance at the expense […]
(par 3. 4.2) Energy in Ecosystems
http://en.wikibooks.org/wiki/Ecology/Energy_in_ecosystems An example of the concept of energy flow through trophic levels of a food chain. 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 […]
