10. Food web (trophic „chain“) Producers (green plants, algae, autotrophic bacteria) Primary consumers (herbivores) Secodary consumers (carnivores) Decomposers (heterotrophic bacteria, fungi) Decay of organic matter Release of inorganic nutrients Solar energy
11. Energy flow within food web Biomass of producers Biomass of primary consumers Loss of energy Loss of energy Biomass of secondary consumers
