What do you understand by biogeochemical cycles?
The balance of the chemical elements in the atmosphere and hydrosphere is maintained by a cyclic passage through the tissues of plants and animals. The cycle starts by absorbing chemical elements by the organism and returned back to air, water, and soil through decomposition. These cycles are energized by solar insolation. These cyclic movements of chemical elements of the biosphere between the organism and the environment are referred to as biogeochemical cycles.
