Is a shrimp a producer consumer or decomposer?
The salt water food web begins with producers (plants, algae, phytoplankton) that create food from sunlight, and continues with primary consumers (zooplankton) that eat the producers, followed by secondary consumers (shrimp, crustaceans, small fish) that eat the primary consumers, then tertiary consumers (large …
