With the help of these biogeochemical cycles, the minerals or substances move to different part of ecosystem by biotic or abiotic pathway.
A cycle is a series of change which comes back to the staring point and which can be repeated.
For eg:- Recycling of water by water cycle in which the water undergoes evaporation, condensation and precipitation, falling back to Earth. Here the way water is travelling to different parts, in the same way the microorganisms move to different parts of the ecosystem through biogeochemical cycles.
