Question

why could we say that biogeochemical cycles are in "balance"?​

Answer 1

1.Biogeochemical cycles include biological,geological, and physiochemical pathways.
2.these occur a continuous dynamism in the cycle,in order to transfer matter and this change is almost kept constant.
3.the stability of this cycle ensures the existence of life on earth.
4.if cycle is sufficiently disturbed by accumulation of any substance at wrong place or wrong state,pollution occurs.
5.so,we can say biogeochemical cycles are in balance naturally.
