👉 Sandimenes are small, round-shaped organisms found in aquatic environments that primarily serve as decomposers. These organisms play a crucial role in nutrient cycling and decomposition processes within aquatic ecosystems by breaking down dead organic matter into simpler compounds that can be used for plant growth or recycle back into the water. Sandimenes also help maintain biodiversity through their roles in the food chain, as they are often preyed upon by larger predators like fish.
