Is common jackknife clam a decomposer?

The common jackknife clam, also known as Ensis directus, is not a decomposer. Instead, it is a bivalve mollusk that primarily feeds on organic matter in the sediment, including detritus and phytoplankton. While it contributes to the ecosystem by recycling nutrients and facilitating sediment aeration, its role is more aligned with being a filter feeder rather than a decomposer. Decomposers are typically organisms like fungi and bacteria that break down dead organic material.
