No, a barnacle is not a decomposer. Barnacles are marine organisms that attach themselves to hard surfaces and filter-feed on plankton and organic particles in the water. Decomposers, such as bacteria and fungi, break down dead organic matter and recycle nutrients back into the ecosystem. While barnacles do contribute to their habitat's ecosystem, they do not perform the role of decomposing organic material.
