Given below are two statements. Statement I - Exchange of phosphorus between organism and the environment is very high. Statement II - Atmospheric inputs of carbon through rainfall are much smaller than phosphorus. In the light of above statements, select the correct option given below:

Options

  1. ABoth statement I and statement II are correct.
  2. BBoth statement I and statement II are incorrect.
  3. CStatement I is correct but statement II is incorrect.
  4. DStatement I is incorrect but statement II is correct.

Correct answer

B. Both statement I and statement II are incorrect.

Step-by-step solution

According to the NCERT Biology textbook, there are two major differences between the carbon and phosphorus cycles: 1. Gaseous exchanges of phosphorus between organisms and the environment are negligible. Therefore, Statement I is incorrect. 2. Atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs. Therefore, Statement II is incorrect. Both Statement I and Statement II are incorrect. Answer: Both statement I and statement II are incorrect.
