Trophic Cascade Calculator

Model how changes in apex predator populations cascade through food chains to affect all trophic levels.

Trophic Level Biomass

Scenario Parameters

Cascade Effect: Top-down control
Apex predators suppress mesopredators, releasing herbivores, which then impact producers
