What are the different feeding levels in ecosystems called?

The different feeding levels in ecosystems are called trophic levels. These levels include producers (autotrophs) at the first level, primary consumers (herbivores) at the second level, secondary consumers (carnivores that eat herbivores) at the third level, and tertiary consumers (top predators) at the fourth level. Decomposers, which break down organic matter, also play a crucial role but are not typically assigned a specific trophic level. Each level represents a step in the flow of energy through the ecosystem.
