Is a velvet worm a decomposer?

No, a velvet worm is not a decomposer. Velvet worms, belonging to the phylum Onychophora, are primarily predators that feed on small invertebrates, such as insects and other arthropods. They play a role in the ecosystem as predators rather than as decomposers, which are organisms that break down dead organic matter. Decomposers include fungi, bacteria, and certain insects that recycle nutrients back into the environment.
