They ask ""what is their impact on the food chain""? Grass shrimp are detritivores which means they eat primarily detritus (organic matter formed by the decomposition of plants). Thus they are very good at processing dead plant matter and moving food energy up the food chain while themselves also serving as food items. Crayfish and grass shrimp will also eat some waste fish food that is lying on plants or the bottom.
