What effect does organic matter in sediments have on nutrient cycling?

• A. It decreases the cycling of nutrients
• B. It facilitates the cycling of essential nutrients
• C. It has no effect on nutrient cycling
• D. It slows down the nutrient absorption

Answer: (B)

Organic matter in sediments plays a crucial role in facilitating the cycling of essential nutrients. When organic materials decompose, they release nutrients such as nitrogen, phosphorus, and carbon back into the surrounding environment, making them available for various biological processes. This process is vital for maintaining healthy ecosystems, as these nutrients are essential for the growth of plants and the overall functioning of marine food webs. Additionally, organic matter can enhance microbial activity in the sediments, which further promotes nutrient cycling. Microorganisms break down organic compounds, and in doing so, they transform nutrients into forms that are more readily accessible to larger organisms within the ecosystem. This interconnectedness supports the productivity of oceanic environments and contributes to the overall health of marine ecosystems.
