Answer: B. Phosphorus is not abundant in the atmosphere, it comes mostly from the land and ocean.

Explanation: The phosphorus cycle differs from other cycles because it does not particularly cycle through the atmosphere, unlike carbon.

The phosphorus that exists in the earth mostly occurs in forms except in gaseous form. This means that it is almost always found in either solid or liquid forms, and never in gaseous form.
