# $\begin{array}{1 1}(A)\;\text{Energy flow in ecosystem is bidirectional}\\(R)\;\text{Energy goes on increasing with each and every trophic level}\end{array}$

$\begin{array}{1 1}(a)\;\text{Both statements are correct & (R) is the correct explanation of (A)} \\ (b)\;\text{Both statements are correct & (R) is not the correct explanation of (A)} \\(c)\;\text{(A) is correct,(R) is false} \\(d)\;\text{(A) & (R) both are incorrect}\end{array}$

(A) & (R) both are incorrect.
Hence (d) is the correct answer.
