Is a seagull a decomposer

No, a seagull is not a decomposer. Seagulls are omnivorous birds that primarily feed on fish, crustaceans, and other small animals, as well as scavenging on dead organisms. Decomposers, such as fungi and bacteria, break down dead organic matter and recycle nutrients back into the ecosystem. Seagulls play a different role in the food web, primarily as consumers.
