Question

Because of biogeochemical cycling,

A. human activity has no effect on elements, chemical compounds, and other forms of matter.

B. living organisms are not limited by any one nutrient.

C. nutrients are circulated throughout the biosphere.

D. many nutrients do not reach toxic concentrations in the biosphere.

Answer 1

i think its C since biogeochemical cycle cycle nutients (which are chemicals) in the biosphere.

Answer 2

it is c

Answer 3

Consider this. A is not the answer because human activities have effects on the elements, chemical compounds and matters. E.g human activities can affect nitrogen and carbon fixation. B is not because there are micro and macro nutrients passing through biological cycles. C should be the answer because Biogeochemical cycle is the movement and distribution of matter, mainly nutrients between the atmosphere, hydrosphere, lithosphere, and biosphere. D cannot be the answer because many nutrients can reach toxic levels in the biosphere through biomagnification and bioaccumulation along the food chain.

Answer 4

So, C should be the answer.
