Why could we say that biogeochemical cycles are in “balance”? (AS1)

i. Biogeochemical cycles includes both biological, geological and chemical or physicochemical cycles.

ii. The cycles together can be understood like this earth has pool of nutrients.

iii. These nutrients may be of biological origin while others may obtained from rocks and soil (geochemical) in origin.

iv. These interactions consist of transfer of matter and energy between the different components of the biosphere. Biogeochernical pathways determine the path of transfer of matter on earth.

v. These interactions are in dynamic state and they are stable.

vi. The stability of biogeochemical cycles ensures the existence of life on earth.
