Because of biogeochemical cycling,

Ahuman activity has no effect on elements, chemical compounds, and other forms of matter.
Bliving organisms are not limited by any one nutrient.
Cnutrients are circulated throughout the biosphere.
Dmany nutrients do not reach toxic concentrations in the biosphere.

Verified Answer :

Because of biogeochemical cycling, nutrients are circulated throughout the biosphere.
Nutrients and matter are distributed throughout the biosphere, SO it is C.
Human activity does have an effect so it's not A.

Correct answer: C) Nutrients are circulated throughout the biosphere

Biogeochemical cycles are cycles by which essential elements of a living organism are circulated continuously. It consider the biological, chemical, and geological aspect of each cycle.

The most important biogeochemical cycles are nitrogen cycle, carbon cycle, water cycle, oxygen cycle and phosphorous cycle.

Biogeochemical cycle always have a state of equilibrium, and the state of equilibrium is attained when there is balance in cycling of element among the compartment.
