Show Answer

Correct Answer :

Option A

Biogeochemical cycle

Solution :

The correct answer is Biogeochemical cycle.

Explanation:
A biogeochemical cycle is a natural pathway through which essential matter and chemical elements move through both the biotic (living organisms) and abiotic (atmosphere, hydrosphere, and lithosphere) components of the Earth.

Biogeochemical cycles are broadly classified into two main types based on the location of their principal reservoir:
1. Gaseous Cycles: The main reservoir for the nutrient elements is the atmosphere or the hydrosphere. Examples include the carbon cycle, nitrogen cycle, oxygen cycle, and water cycle.
2. Sedimentary Cycles: The main reservoir for the nutrient elements is the Earth's crust (rocks, soil, and minerals). Examples include the phosphorus cycle and sulfur cycle.

Therefore, the cycle that consists of both sedimentary and gaseous cycles is the biogeochemical cycle.
