Is a oligochaeta worm a herbivore?

Oligochaeta, a class of annelid worms that includes earthworms, are generally detritivores rather than strict herbivores. They feed primarily on decomposing organic matter, such as dead plant material and microorganisms in the soil. While they may consume plant material, their role in the ecosystem is more about recycling nutrients and improving soil structure than directly feeding on living plants.
