Trophic flow
WebJan 25, 2024 · A trophic level depends on the trophic level beneath it because it consumes and absorbs energy from the lower trophic level. Image Credit: CK12-Foundation What is a Food Chain? The direction of the flow of energy or biomass within an ecosystem is determined by the food chain, a linear channel inside a food web. WebEach organism in a food chain occupies a specific trophic level (energy level), its position in the food chain or food web. In many ecosystems, the base, or foundation, of the food chain consists of photosynthetic organisms (plants or phytoplankton), which are called producers.
