What is the function of decomposers in Biogeochemical cycles?
In Biogeochemical cycles, decomposers play a major role. hey decompose the dead bodies (of plant and animals) and excreta of both plants and animals. These bacteria convert the complex sunstances into the simpler forms. The compounds are released into nutrient pool (soil, water bodies, atmosphere) and the elements are put back into circulation by plants through reabsorption from the soil.
