Question

Biogeochemical cycles are also known as:

• A. Sedimentary cycles
• B. Gaseous cycles
• C. Material cycles
• D. Cycles of water

Answer 1

The correct option is C

Material cycles

The correct answer is Option C

The explanation for the correct answer:

Biogeochemical cycles :

1. The pathways through which elements such as carbon-nitrogen and oxygen move from the environment to living organisms and get back to the environment are termed biogeochemical pathways.
2. The term Biogeochemical, word bio refers to living organisms and geo refers to rocks, soil air, and water.
3. These cycles are known as biogeochemical cycles as these cycles link the biotic factors of the environment with abiotic factors.

Explanation of the incorrect answer:

Option A: Sedimentary Cycles

1. The cycles in which the reservoir for the nutrient elements is present in the sediments of the earth.
2. These cycles are slow and less perfect as their elements get locked in the reservoir pool and go out of circulation for a long period.
3. The Elements such as Sulphur, Phosphorus, Potassium, and Calcium have sedimentary cycles.

Option B: Gaseous Cycles

1. The cycles in which the reservoir for the nutrient elements is present in the atmosphere or hydrosphere.
2. These cycles are quick and perfect as the flow of nutrient elements is uniform.
3. The most abundant elements found in living organisms are Carbon, Hydrogen, Oxygen, and Hydrogen have gaseous cycles.

Option D: Cycles of water

1. The continuous movement of water on, above, and below the surface of the earth is called the water cycle.
2. It is the state of change of water into liquid, vapors, and ice in the environment at various places.
3. The cycles of water include biological and global cycles.

Final answer: The correct answer is option (C)
