The carbon, oxygen, and nitrogen cycles allow vital elements to return to usable form by organisms.. c.. The carbon, oxygen, and nitrogen cycles are an important interface between biotic and abiotic factors.. d.. All of the above are reasons the carbon, oxygen, and nitrogen cycles are vital to life on Earth

Answer 1

The correct answer is (D)

All the above are reasons the carbon , oxygen, and nitrogen cycles are vital to life on earth.

The explanation:

because :

1) Carbon, oxygen, and nitrogen are vital components of life on Earth.

2) The carbon, oxygen, and nitrogen cycles allow vital elements to return to usable form by organisms.

3)The carbon, oxygen, and nitrogen cycles are an important interface between biotic and abiotic factors

4) They are all biogeochemical cycles.

5) They all involve an interaction between living and nonliving elements.

6)They are all part of the Earth system.

Answer 2

The correct answer among the choices listed is option D. Carbon, oxygen, and nitrogen cycles vital to sustaining life on Earth because they are vital components of life, vital elements to return to usable form by organisms and an important interface between biotic and abiotic factors.
