Definition

Detrital food webs are ecological networks that decompose and recycle organic matter from dead plants, animals, and waste products. These webs play a crucial role in nutrient cycling and energy flow within ecosystems.

5 Must Know Facts For Your Next Test

  1. Detrital food webs rely on decomposers like bacteria and fungi to break down organic material.
  2. These systems help convert dead organic matter into simpler substances that can be reused by primary producers.
  3. Detritivores, such as earthworms and certain insects, are key players in detrital food webs.
  4. They operate alongside grazing food webs to maintain ecosystem balance.
  5. Energy transfer in detrital food webs is less direct compared to grazing food webs.
