Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
raketka [301]

From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.

---------------------------------------

  • Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level.

  • From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.  

  • At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule".

  • This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

  • The progressive reduction of energy determines the number of trophic levels (4 or 5).  

If <u>30,000,000 MJ</u> of Sunlight (solar energy) reaches ground, then only <u>30,000 MJ</u> can be absorbed by primary producers.

<u>5,216.4 MJ</u> from 52,164 MJ of energy stored in the <u>soybeans</u>, are used by cattle.

 

1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.

<u>164.5 MJ </u>of this energy is tranferred to the following trophic level.
