What is the role of shredders in nutrient cycling?

• A. To filter fine particles from water
• B. To fragment organic particles while consuming bacteria and fungi
• C. To graze on algae on surfaces
• D. To decompose particulate organic matter

Answer: (B)

Shredders play a crucial role in nutrient cycling by fragmenting organic particles while simultaneously consuming bacteria and fungi that reside on these particles. This process not only breaks down larger organic matter into smaller pieces, which can then be further decomposed by microorganisms, but also enhances the microbial community by providing food sources. As shredders consume these organic materials, they help increase the surface area available for microbial colonization, thereby accelerating the decomposition process. This interaction is essential for nutrient cycling in ecosystems, as it contributes to the release of nutrients back into the environment, making them available for uptake by plants and other organisms. In this way, shredders facilitate the transformation and flow of nutrients through the ecosystem, supporting overall ecological health and productivity.
