Question:
There is a loss of energy at each step in a food chain. I was wondering what natural law does that illustrate? What structure is created by that process?



Replies:
Look up the Ecological Energy Pyramid and the 10 percent rule. This is what you are after.

This sounds like a homework problem. I'll give you my answer, and you can try to explain it. The natural law it illustrates is the second law of thermodynamics; entropy is created in any natural trnasfer of energy.

Richard E. Barrans Jr.


This illustrates the law of entropy. This law observes that whenever there is a transfer or transformation of energy some of the energy is transformed into a form that is less useful (effectively 'lost' although it is not destroyed - only in a less useful form).

You may be asking about energy pyramids. These are graphs that show the total energy found at each level of a food chain. The lowest level (producers) is the widest. With every upward step (first order consumer, second order consumer...) the pyramid becomes narrower as energy is lost fromt he system.

I hope this information is useful.
