The model here is not found but matter and energy flow in a food web from lower trophic levels to higher levels.
Energy transfer in the ecosystem describes how energy flows along the food web (most energy is lost as heat).
When one organism eats another the biomass flows from the lower trophic levels to the higher level, and this process requires digestive enzymes.
In conclusion, the model here is not found but matter and energy flow in a food web from lower trophic levels to higher levels.
