Which of these is not a correct difference between carbon cycle and phosphorus cycle?
Options
- ACarbon cycle is a gaseous type of nutrient cycle while Phosphorus cycle is a sedimentary type of nutrient cycl
- BThe reservoir of carbon is ocean while the reservoir of phosphorus is rock
- CIn carbon cycle, there is respiratory release of carbon into atmosphere while this doesn't happen in phosphoru
- DAtmospheric inputs of phosphorus through rainfall are much larger than carbon inputs
Correct answer
D. Atmospheric inputs of phosphorus through rainfall are much larger than carbon inputs
Step-by-step solution
The reservoir for gaseous type of nutrient cycle (e.g., nitrogen, carbon cycle) exists in the atmosphere and for the sedimentary cycle (e.g., sulphur and phosphorus cycle), the reservoir is located in Earth's crust. 71% of carbon is found dissolved in oceans. The natural reservoir of phosphorus is rock, which contains phosphorus in the form of phosphates. Unlike the carbon cycle, there is no respiratory release of phosphorus into the atmosphere. Atmospheric inputs of phosphorus through rainfall are much smaller tha
