# Which of the following is present in carbon cycle but absent in phosphorous cycle:-

$\begin{array}{1 1}(a)\;\text{Atmospheric inputs via rainfall}\\(b)\;\text{Rock animals are reservoirs}\\(c)\;\text{Gaseous exchange b/w organism & environment}\\(d)\;\text{Reposition due to decomposition}\end{array}$

Gaseous exchange b/w organism & environment is present in carbon cycle but absent in phosphorous cycle
Hence (c) is the correct answer.
