10 Percent Rule
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?
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.
