Within enclosed ecosystems designed to function with minimal human intervention, natural recycling becomes the foundation of long-term stability, and this is where Investigating Decomposition Processes Supported by Isopods in Closed Bioactive Setups gains its relevance. Bioactive environments rely on living organisms to break down organic waste and return nutrients to the system in a balanced way. Isopods, often referred to as clean-up organisms, play a central role in this process by feeding on decaying plant matter, shed skin, and leftover organic debris. Their constant movement through the substrate helps fragment larger waste into smaller particles, increasing surface area for microbial activity. This interaction speeds up decomposition while preventing waste buildup that could otherwise harm plants or animals. In a closed setup, where manual cleaning is limited, such efficiency becomes essential. The presence of isopods supports a self-regulating cycle that mirrors natural soil...
