(par 3. 5 ) Energy-flow through the ecosystem
http://www.mansfield.ohio-state.edu/~sabedon/campbl54.htm FLOW OF ENERGY THROUGH ECOSYSTEMS (1) Ecosystem (a) “An ecosystem consists of all the organisms living in a community as well as all the abiotic factors with which they interact.” (b) Note that the boundaries of ecosystems are typically not arbitrarily defined, but instead are defined in some meaningful way: A pond, a field, a forest, […]
(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 […]
