The cyclic flow of nutrients within an ecosystem is called as the bio-geochemical cycle.
A continuous transfer of nutrients which are necessary for the growth of organisms occurs from abiotic to biotic factors and biotic to abiotic factors in an ecosystem.
This nutrient cycle operates continuously through the biosphere formed by lithosphere, atmosphere and hydrosphere.
Soil bacteria and other decomposers play vital role in these cycles.
The recycling of these bio-geo-chemicals depends upon the level of energy transfer in the ecosystem.
Any type of disturbance at any level of these cycles affects the ecosystems and destroy nature's balance.
Hence, there should be equilibrium in the various bio-geochemical cycles.
