Identify the incorrect statement from the following.

Options

  1. AReservoir pool for phosphorus cycle is earth's crust whereas atmosphere is the reservoir pool for carbon cycle
  2. BDuring carbon cycle and phosphorus cycle, there is very little respiratory release of carbon and phosphorus.
  3. CAtmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs.
  4. 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
