Question

Some of the nutrient cycles are labeled as below.
Sulphur cycle (A), phosphorus cycle (B), carbon cycle (C), and nitrogen cycle (D). Of these, the sedimentary cycle is represented by:

• A. (A) only
• B. (B) only
• C. (C) only
• D. (A) and (B) only
• E. (C) and (D) only

Answer 1

The correct option is D (A) and (B) only

The sedimentary cycle is one of the biogeochemical cycles that forms an important factor for the growth and development of a living organism. For the sedimentary cycle, the major reservoir is the lithosphere which releases the elements through weathering. The mineral elements required by living organisms are obtained from inorganic sources either from salts dissolved in water or from rocks. The sedimentary cycle is represented by phosphorus, sulphur, and iodine cycles.
Sulphur cycle is the cycle that allows the circulation of sulphur from the source to the various living organisms and back to the natural resources in form of salts of sulphur.

Phosphorus cycle is the cycle that allows the circulation of phosphorus from the source to the various living organisms and back to the natural resources in form of salts of phosphorus.
