Biogeochemical Cycles

Biogeochemical Cycles

‘Bio’ refers to living organisms and ‘geo’ to the air, water and soil of the earth. Chemical elements tend to circulate in a characteristic path—from the environment to organisms and back to the environment. These more or less circular paths are known as biogeochemical cycles or nutrient cycles. Circulation of various nutrients between the living and nonliving components of ecosystems are called biogeochemical cycles. During these cycles, inorganic nutrients get converted into food.
