Vedclass · Answer

(A, B) The $DFC$ (Detritus Food Chain) begins with dead organic matter. Decomposers like bacteria and fungi are saprotrophs,not parasites. Therefore,statement $A$ is incorrect as they are saprotrophic decomposers. In aquatic ecosystems,the $GFC$ (Grazing Food Chain) is the major conduit for energy flow,whereas in terrestrial ecosystems,the $DFC$ is the major conduit. Thus,statement $B$ is also incorrect. $DFC$ and $GFC$ are interconnected because organisms of $DFC$ can serve as prey for $GFC$ animals,and $GFC$ waste enters the $DFC$.
