20. Can the amount of
available energy in a given
trophic level be larger than
the available energy in inferior
trophic levels? What does that
condition means to the
conformation of the energy
pyramids?

A superior trophic level has less
available energy inferior trophic
levels. This because in each trophic
only a fraction of organic
material of the below is
incorporated into consumers (into
their bodies). other part is
eliminated or is used in
metabolism as energy source.
it is never possible have energy
pyramids with conformation,
i.e., with the to the bottom and
base to the top. is also not possible
have superior trophic levels a
variable dimension larger inferior
ones. In every pyramid, from
the base the top, the size the
variable dimension decreases.
