(par 3. 4.1) Trophic levels and the effects of biomass on availablity of energy
http://www.marietta.edu/~biol/102/ecosystem.html Overview The main concepts we are trying to get across in this section concern how energy moves through an ecosystem. If you can understand this, you are in good shape, because then you have an idea of how ecosystems are balanced, how they may be affected by human activities, and how pollutants will move […]
(par 3. 4 ) Ordered biologigal systems and Enthropy
Biological Systems are highly ordered. How does it square up with Enthropy? http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/bioentropy.html#c1 Energy and Order in Biological Systems The concept of entropy and the second law of thermodynamics suggests that systems naturally progress from order to disorder. If so, how do biological systems develop and maintain such a high degree of order? Is this […]
(par 3. 4 ) 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 of potential energy. Conversion of […]
