How are the carbon, nitrogen, and oxygen cycles similar? a) they are all biogeochemical cycles b) they all involve an interaction between living and non living elements c) they are all part of the earth system d) all of the above

The carbon, nitrogen, oxygen cycles are all biogeochmeical cycles in which the three elements are fixed into the enironment in different forms, to utiization, for conservation, and transfer from one organsim to another. They all involve interaction between living and non living things, and are part of earth system. So the correct answer is D.

The carbon, nitrogen, and oxygen cycles similar as they are all biogeochemical cycles, they all involve an interaction between living and non living elements and they are all part of the earth system. Therefore the answer is letter D. I hope the answer helps.
