Question

value: 3
which of the following the pathway by which a chemical substance moves through biotic and abiotic compartments of the earth?
○ a. nitrogen cycle
○ b. biogeochemical cycle
○ c. carbon cycle
○ d. sulfur cycle

Explanation:

To solve this, we analyze each option:

• Option a (Nitrogen cycle) is a specific type of cycle for nitrogen, not a general term for chemical substance movement through biotic and abiotic compartments.
• Option b (Biogeochemical cycle) is defined as the pathway by which a chemical substance moves through biotic (living) and abiotic (non - living) compartments of the Earth. This matches the description in the question.
• Option c (Carbon cycle) is a specific cycle for carbon, not a general term for all chemical substances.
• Option d (Sulfur cycle) is a specific cycle for sulfur, not a general term for all chemical substances.

Answer:

b. Biogeochemical cycle
