NO - you're thinking of a scavenger - A filter feeder eats plankton and other small particles in the sea. They pull water through their body, straining it for food - push the
water back out and eat any solids found.
An earthworm is not a filter feeder. Marine animals that feed by passing nutrient-rich water through their gills are called filter feeders because their gills filter nutrients from the water and pass them into their intestines. An earthworm does not have gills and does not normally live in water. The earthworm's digestive system consists of a pharynx, esophagus, crop (food receptacle), gizzard (used for grinding swallowed earth), and a long, straight intestine.
