Vedclass · Answer

(C) Statement $X$ is true because phosphorus is a sedimentary cycle,and its atmospheric input through rainfall is significantly lower compared to the carbon cycle,which relies heavily on atmospheric $CO_2$.Statement $Y$ is false because the exchange of phosphorus between organisms and the environment is not negligible; it is a vital nutrient that cycles through food chains,decomposition,and weathering processes,although it lacks a significant gaseous phase.

$X-$ Atmospheric input of phosphorus through rainfall is much smaller than carbon input.
$Y-$ The exchange of phosphorus between organisms and the environment is negligible.
