What is a decomposer in the ocen?

In the ocean, decomposers are organisms that break down dead organic matter, facilitating nutrient recycling within marine ecosystems. Key decomposers include bacteria, fungi, and certain invertebrates like worms and sea cucumbers. These organisms help decompose organic material, returning essential nutrients to the water, which supports the growth of primary producers like phytoplankton. By breaking down waste and dead organisms, decomposers play a crucial role in maintaining the health and balance of ocean ecosystems.
