The great pond snail (Lymnaea stagnalis) is not a decomposer; it is primarily a herbivore that feeds on aquatic vegetation and detritus. While it may contribute to the breakdown of organic matter by grazing on decaying plant material, it does not perform the specific ecological role of a decomposer like bacteria or fungi. Instead, it plays a role in the ecosystem by helping to control plant growth and providing food for predators.
Most are, but some are carnivorous.
