sci.trophic-transfer-efficiency Calculator
Calculates trophic transfer efficiency between levels in a food web: TE = production at level n+1 / production at level n, typically 5–20%. At 10% efficiency, 1,000 kg of phytoplankton supports 10 kg of zooplankton → 1 kg of small fish → 0.1 kg of large fish — this pyramid limits the size of top predator populations.
Inputs
P Primary Kj
Reference formula or conversion factor shown for context.
Te Pct
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Trophic Levels
Count of items or occurrences.
Results
energy at apex predator (kJ/yr)
The value at the specified point or condition.
fraction reaching apex level
The measured or computed level on the applicable scale.
energy at herbivore level (kJ/yr)
The measured or computed level on the applicable scale.
