Which of the following is NOT true of phosphorus and the phosphorus cycle?

Phosphorus is mined from phosphorus rich rock, which is processed and then added to commercial inorganic fertilizers as well as detergents.

Phosphorus tends to be more localized compared with other biogeochemical cycles that can move more freely in the global system.

Phosphorus is generally found in rocks, sediments, and soil.

Phosphorus does not exist in the atmosphere as a gas.

Living organisms do not need phosphorus.
