What is the Biogeochemical Cycle
What is the Biogeochemical Cycle Biogenic elements (macro-, micro- & other elements) flow from the environment into and out of the plant in a cyclic manner. This flow of nutrients from abiotic to biotic components of the ecosystem and vice-versa constitute the biogeochemical cycles.Hydrological or Water Cycle :Water on earth is cycled by two processes, … [Read more...] about What is the Biogeochemical Cycle
