_______ is/are a crucial nutrient reservoir of phosphorus that is available to organisms.

Question

Quizplus · Accepted Answer

Phosphorus is primarily stored in rocks and minerals, and is released through weathering and erosion over time. This makes rocks a crucial nutrient reservoir of phosphorus that is available to organisms. The atmosphere does not contain significant amounts of phosphorus, and while phosphorus is present in oceans and other bodies of water, it is typically not as readily available to organisms as the phosphorus in rocks. Autotrophs and consumers require phosphorus as a nutrient, but they do not serve as a reservoir for this nutrient.
