Biomass decreases at each trophic level because only a small proportion of ingested food is converted into new tissue, storing energy. Biomass is equated to energy content, and this inefficient conversion leads to a decrease in biomass at each level.
La biomassa diminuisce in ogni livello trofico perché solo una piccola proporzione del cibo ingerito viene convertita in nuovo tessuto, immagazzinando energia. La biomassa è equivalente al contenuto energetico, e questa conversione inefficiente porta a una diminuzione della biomassa ad ogni livello.
