What food chain is the crayfish part of?

Crayfish are typically part of freshwater food chains, serving as both predators and prey. They primarily feed on detritus, aquatic plants, and small invertebrates, positioning them as scavengers and consumers. In turn, they are preyed upon by a variety of animals, including fish, birds, and mammals, thus playing a crucial role in the ecosystem as both a food source and a contributor to nutrient cycling.
