👉 Rhizamoeba is a protozoan that inhabits soil, roots, and other plant structures, primarily in aquatic environments. It plays a crucial role in nutrient cycling by absorbing nutrients from the soil through its root system, which can be up to 100 times larger than its body size. Rhizamoebas feed on organic matter and are responsible for maintaining soil health by breaking down dead matter into nutrients that plants can absorb.
