Earth’s largest phosphorus reservoir is _______.
- a. the atmosphere
- b. the ocean
- c. sedimentary rock
- d. living organisms
Concept introduction: Atoms of phosphorus are highly reactive. Therefore, phosphorus does not occur naturally in its elemental form. Most of the earth’s phosphorus is bonded to oxygen molecule as phosphate (PO43-). Phosphorus cycle is the movement of phosphorus among Earth’s rocks and waters and into and out of food webs.
Reasons for the correct statement:
Earth’s crust is the largest reservoir of phosphorus that is an element that does not occur as a gas in any significant quantity. It is an ion that abounds in rocks and sediments. In the phosphorous cycle, phosphorus passes quickly through food webs as it moves from land to ocean sediments, then back to the lands. This is because little phosphorus exists in a gaseous form and its major reservoir is sedimentary rock.
Option c. is given as “sedimentary rock”.
Earth’s largest phosphorus reservoir is sedimentary rock. Therefore, option c. is correct.
Reasons for the incorrect statements:
Option a...
