Biology

The correct answer is: D.Phosphorus

Phosphorus is the only nutrient in this list that does not cycle through the atmosphere. Instead, it stays primarily in the soil, rocks, and water. Phosphorus is released into the environment through the weathering of rocks and is taken up by plants and other organisms in the form of phosphate (PO₄³⁻). It does not have a significant gaseous phase like carbon or nitrogen.

Explanation of the other nutrients:

A.Carbon: Carbon is cycled through the atmosphere as carbon dioxide (CO₂), and it also moves through living organisms, oceans, and soils in the carbon cycle.
