Which of the following statements is FALSE about the Phosphorus Cycle?
Options
- AAtmospheric inputs of phosphorus through rainfall are meagre.
- BGaseous exchange of phosphorus between organisms and the environment are negligible.
- CPhosphorus does not act as a limiting factor for plant growth.
- DAgricultural runoff rich in phosphate content leads to eutrophication.
Correct answer
C. Phosphorus does not act as a limiting factor for plant growth.
Step-by-step solution
Analyzing each statement regarding the Phosphorus Cycle: Statement (1): Unlike the carbon cycle, atmospheric inputs of phosphorus through rainfall are indeed much smaller. This statement is true. Statement (2): Phosphorus is a sedimentary cycle. There is no significant respiratory release or gaseous phase for phosphorus, meaning gaseous exchange between organisms and the environment is negligible. This statement is true. Statement (3): Phosphorus is an essential macronutrient for plants. In many ecosystems, its ava
