Grazing Food Chain vs. Detritus Food Chain: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 2, 2023
Grazing food chain involves direct transfer of energy from plants to herbivores while, detritus food chain derives energy from breaking down dead organic matter.

Key Differences

The grazing food chain begins with living plants or producers, providing energy directly to primary consumers or herbivores.

In contrast, the detritus food chain starts not with living plants but with dead organic matter, which is consumed by organisms known as decomposers.

In a grazing food chain, energy flows from plants (producers) to herbivores (primary consumers) and then to carnivores (secondary and tertiary consumers).
