Q33 / 200 · MHT CET - Medical 2026 (24 April Shift 1) · Biology

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:

  • A
    Both statement I and statement II are correct.
  • Correct answer
    B
    Both statement I and statement II are incorrect.
  • C
    Statement I is correct but statement II is incorrect.
  • D
    Statement I is incorrect but statement II is correct.

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.

Hence, the correct answer is option: 'B'.
