AI Thread Summary
In marine ecosystems, decomposer microorganisms, particularly bacteria, play a crucial role in nutrient cycling, similar to their counterparts on land. Additionally, various worm species, such as shipworms, contribute significantly to the decomposition process, especially in breaking down wood. These organisms are essential for maintaining the health and balance of oceanic environments.
