Explanation:

Nutrient cycling is the movement of  matter within the ecosystem.

A general model of nutrient cycling includes the main reservoirs  of elements and the processes by which these elements are transferred between the two reservoirs.

One of these two reservoirs include the organic materials that form biotic pool. The other reservoir include the inorganic matter that form the abiotic pool.

The biotic component obtain the nutrient from the abiotic pool through the food chain.

While these nutrients are transferred back to the abiotic pool by the decomposition of detritus by decomposers.

Sulfur and Phosphorus being nutrients are transferred from biotic to abiotic pool by decomposition of organic detritus.
