Given below are two statements regarding carbon and phosphorus...
Given below are two statements regarding carbon and phosphorus cycles.
Statement (I): Atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs.
Statement (II): Exchange of phosphorus between organisms and the environment is huge as compared to carbon.
In light of the above statements, choose the most appropriate answer from the options given below.
Statement (I): Atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs.
Statement (II): Exchange of phosphorus between organisms and the environment is huge as compared to carbon.
In light of the above statements, choose the most appropriate answer from the options given below.
Options
- ABoth Statement (I) and Statement (II) are correct.
- BBoth Statement (I) and Statement (II) are incorrect.
- CStatement (I) is correct but Statement (II) is incorrect.
- DStatement (I) is incorrect but Statement (II) is correct.
Correct answer
C. Statement (I) is correct but Statement (II) is incorrect.
Step-by-step solution
According to the NCERT Biology textbook, there are two major differences between the carbon and phosphorus cycles.
Firstly, atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs. Thus, Statement (I) is correct.
Secondly, gaseous exchanges of phosphorus between organisms and the environment are negligible, whereas carbon exchange is significant. Thus, Statement (II) is incorrect.
Therefore, Statement (I) is correct but Statement (II) is incorrect.
Answer: Statement (I) is correct but Statement (II) is incorrect.
Firstly, atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs. Thus, Statement (I) is correct.
Secondly, gaseous exchanges of phosphorus between organisms and the environment are negligible, whereas carbon exchange is significant. Thus, Statement (II) is incorrect.
Therefore, Statement (I) is correct but Statement (II) is incorrect.
Answer: Statement (I) is correct but Statement (II) is incorrect.
