Question

Biogeochemical cycles

• A. Include the processes only conducted by or within living organisms
• B. Pertain only to the abiotic environment
• C. Describe the movement of water and other materials throughout the abiotic and biotic environment
• D. Are used to describe the attempts of humans to recycle various pollutants

Answer 1

The correct option is C Describe the movement of water and other materials throughout the abiotic and biotic environment

Breaking apart the word biogeochemical into pieces. The first part of the word, bio, involves biological organisms, like bacteria, plants, and animals. The next part of the word, geo, involves geological processes, like the weathering of rocks. The last part of the word indicates chemical processes, such as the formation of molecules. Thus a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. A cycle is a series of change which comes back to the starting point and which can be repeated.

So, the correct answer is 'Describe the movement of water and other materials throughout the abiotic and biotic environment'.
