Answer 2

Answer:

(d) Rocks

The largest reservoir of Sulphur and phosphorus in biosphere is Rocks.

Explanation:

The ocean is the world's largest Sulphur reservoir, with large amounts in the form of dissolved sulphate and sedimentary minerals (e.g., gypsum and pyrite). Sulphate is the most stable form of Sulphur on the planet, and its main sources in the ocean are weathering and leaching of rocks and sediments. Sulphur is mostly found in seawater or sedimentary rocks, particularly pyrite-rich shales and evaporite rocks. The largest phosphorous reservoir is sedimentary rocks. Phosphates are removed from rocks by weathering and are distributed in soils and water. Plants absorb phosphate ions from the soil.
