    Consider the following statements. Animals need large quantities...
    Explanation:

    Phosphorus is an essential element for all living organisms. It is a key component of nucleic acids, ATP, and cell membranes. It is also needed by animals to make shells, bones, and teeth.

    Natural Reservoir of Phosphorus:

    The natural reservoir of phosphorus is rock. Phosphorus is released from rocks through weathering and erosion. This process takes a long time, and it is the reason why phosphorus is often a limiting factor in ecosystems.

    Respiratory Release of Phosphorus:

    Unlike the carbon cycle, there is no respiratory release of phosphorus into the atmosphere. Phosphorus cycles through the biosphere, lithosphere, and hydrosphere, but it does not cycle through the atmosphere.

    Conclusion:

    Therefore, statement 1 and 2 are correct. Statement 3 is incorrect, as there is no respiratory release of phosphorus into the atmosphere. The correct answer is option C, 1 and 2 only.

    Consider the following statements. Animals need large quantities...
    Option (c) is the correct answer.
    Phosphorus is a major constituent of biological membranes, nucleic acids and cellular energy transfer systems.
    • Statement 1 is correct. Many animals also need large quantities of this element to make shells, bones and teeth.
    • Statement 2 is correct. The natural reservoir of phosphorus is rock, which contains phosphorus in the form of phosphates. When rocks are weathered, minute amounts of these phosphates dissolve in soil solution and are absorbed by the roots of the plants. Herbivores and other animals obtain this element from plants. The waste products and the dead organisms are decomposed by phosphate-solubilising bacteria releasing phosphorus.
    • Statement 3 is incorrect. Unlike carbon cycles, there is no respiratory release of phosphorus into the atmosphere.
