Verified by Experts

The correct Answer is:
D
As the earth is essentially a closed system with respect to matter we can say that all matter on earth cycles. Every matter that is used by living organisms passes between biotic and abiotic components of the biosphere. The whole of biogenetic nutrients are not always in circulation. For example rocks from which nutrients are very slowly transferred to the cycling pool.
