Which of the following best describes a beneficial role of saprophytes?

The beneficial role of saprophytes is primarily to decompose dead organic matter. Saprophytes are organisms, often fungi or bacteria, that play a crucial role in nutrient cycling within ecosystems. By breaking down decaying plant and animal materials, they convert complex organic substances back into simpler molecules. This process enriches the soil with essential nutrients, making them available for uptake by living plants, thereby promoting healthy growth in the ecosystem.

The decomposition process facilitated by saprophytes is vital for maintaining soil health and fertility. Without these organisms, dead organic material would accumulate, leading to a decrease in soil quality and hindering the growth of new vegetation. Thus, saprophytes contribute significantly to the overall health and productivity of agricultural systems and natural habitats alike.
