The simplest of all nutrient cycles operating in an ecosystem is______ cycle

Step-by-step solution

U nlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on earth. It is absorbed by autotrophs, at each level excess phosphorus is eliminated and decomposers return them to the soil so that autotrophs can reobtain them.
