Answer:
Phosphorus isn't as abundant as nitrogen or carbon because it is contained in the lithosphere and released with geological processes, which can take a long time.
Answer: Lithosphere and geological
Explanation: The phosphorus is not as abundant as carbon because it does not occurs in the form of gas.
The phosphorous cycle is completed in the lithosphere as well as geological process which takes time. It is contained in the rocks and gets run off through water after weathering.This is how the plants get phosphorous from soil and water.
The run off then flows towards ocean and sea and gets deposited in the ocean. This is how phosphorous cycle takes place.
