Identify the incorrect statement from the following.
Options
- AReservoir pool for phosphorus cycle is earth's crust whereas atmosphere is the reservoir pool for carbon cycle
- BDuring carbon cycle and phosphorus cycle, there is very little respiratory release of carbon and phosphorus.
- CAtmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs.
- DGaseous exchanges of phosphorus between organism and environment are negligible.
Correct answer
B. During carbon cycle and phosphorus cycle, there is very little respiratory release of carbon and phosphorus.
Step-by-step solution
In nature, there is a need for continuous recycling of mineral which has have been removed from nature or environment, so some nutrient cycles are operated in nature. These cycles are mainly divided into 2 categories as gaseous cycles (like carbon cycle) and sedimentary cycles (like phosphorous cycle). There are two major and important differences between carbon and phosphorus cycle which are: a Atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs. b Gaseous exchanges of phosphorus
