Question

Which of the following statements about biogeochemical cycles is true?

a) They only include processes conducted by or within living organisms.
b) They pertain only to the abiotic environment.
c) They describe the movement of water and other materials through the biosphere.
d) They only pertain to exchanges and interactions that occur within the atmosphere.
e) They are used to describe the attempts of humans to recycle various pollutants.

Answer 1

Answer:

c) They describe the movement of water and other materials through the biosphere.

Explanation:

A biogeochemical cycle refers to the cyclic series of events. Through this process, nutrients move between the living and nonliving environment. It explains substances such as carbon, nitrogen, and water are cycled between the biotic and abiotic components of the ecosystem. The matter is cycled among the atmosphere, soil and water bodies of the biosphere. For example, the carbon cycle explains the movement of carbon between the atmosphere, living beings,  soil, and the hydrosphere.  

Answer 2

Answer:

The correct answer is - option C.

Explanation:

Various chemical elements and compounds transfer in between atmosphere and living organism or biosphere is known as the biogeochemical cycles.

These transfers include various life process performed by the organisms such as food chain helps in ingesting or absorb these chemicals and compounds and then returned to the atmosphere and soil by respiration, decomposition, and excretion. These chemicals are carbon, nitrogen, oxygen, and water.

Thus, the correct answer is - option C.
