Question
Distinguish between : Carbon cycle and phosphorus cycle.
| Carbon cycle | Phosphorus cycle |
| $1.$ Carbon cycle is a gaseous cycle. | $1.$ Phosphorus cycle is a sedimentary cycle. |
| $2.$ Carbon cycle has higher speed. | $2.$ Phosphorus cycle is very slow. |
| $3.$ There is respiratory release of $CO_2$ in carbon cycle. | $3.$ There is no respiratory release of phosphorus. |
| $4.$ Atmospheric inputs of carbon through rainfall are larger. | $4.$ Atmospheric inputs of phosphorus through rainfall are much smaller. |
| $5.$ Exchanges of phosphorus between organism and environment are negligible in carbon cycle due to photosynthesis and respiration. | $5.$ Exchanges of phosphorus between organism and environment are negligible in phosphorus cycle. |
