_________Q________ : reservoir is located in the Earth’s crust : Sulphur cycle

• A. P - Gaseous cycle, Q- Sedimentary cycle, R - Phosphorus cycle
• B. P - Gaseous cycle, Q- Sedimentary cycle, R - Carbon cycle
• C. P - Sedimentary cycle, Q- Gaseous cycle, R - Oxygen cycle
• D. P - Sedimentary cycle, Q- Gaseous cycle, R - Nitrogen cycle

Answer 1

The correct option is B P - Gaseous cycle, Q- Sedimentary cycle, R - Carbon cycle

Movement of nutrients occurs through various biotic and abiotic components of the ecosystem and is termed as biogeochemical cycles. It is of two types based on the reservoirs -

• Gaseous cycle - The reservoir exists in the atmosphere. Example: Nitrogen, carbon, etc.
• Sedimentary cycle - The reservoir exists in the earth’s crust. Examples : Sulphur, phosphorus, etc.
