Answer:
The Phosphorus Cycle, in contrast to the other cycles, does not include a gas stage and only takes place in land and water environments - not in the atmosphere.
Explanation:
The Phosphorus Cycle is a biogeochemical cycle in which <em>phosphorus</em>, a chemical element, <em>circulates around the lithosphere, hydrosphere, and the biosphere.</em> This indicates that, <u>in contrast to the Water, Carbon, and Nitrogen Cycles, this cycle does not include a gas stage and only takes place in land and water environments.</u>
The Water, Carbon, and Nitrogen Cycles, on the other hand, are biogeochemical cycles in which their chemical elements also circulate around land and water but, in contrast to phosphorus, they move around the atmosphere.
