Quizplus · Accepted Answer

Phosphorus is primarily derived from weathered rock and soil minerals. It is taken up by plants and then passed through the food chain to animals, where it becomes incorporated into biological tissues. While some phosphorus can be found in the ocean and volcanic activity can cause some release of phosphorus, the majority of phosphorus in biological tissues can be traced back to weathered rock.
