What does the subphylum crustacea eat?

Answer 1

Crustaceans have diverse diets that vary by species, but they generally feed on organic matter, including detritus, algae, plankton, and smaller animals. Many are filter feeders, using specialized appendages to capture food particles from the water, while others are scavengers or predators, consuming dead organisms or hunting live prey. Some crustaceans, like shrimp and crabs, may also eat plant material in addition to animal matter. Overall, their feeding habits play a crucial role in aquatic ecosystems.
