Effects of biomass changes in the supply–demand balance of energy in aquatic food webs.

Highlights: [•] Supply–demand balance of energy of food webs is sensitive to biomass of species. [•] Changes in autotrophic biomass increase the oversupply of resources. [•] Changes in heterotrophic biomass decrease the oversupply of resources. [•] Oversupply increases are related to a flow control bottom-up. [•] Oversupply decreases are related to a flow control top-down. [Copyright &y& Elsevier]
