Name the type of food chains responsible for the flow of larger fraction of energy in an aquatic ecosystem and a terrestrial ecosystem, respectively. Mention any two differences between the two food chains.

In an aquatic ecosystem-Grazing food chain (GFC). In a terrestrial ecosystem-Detritus food chain (DFC). Differences – Grazing Food Chain Detritus food chain Transfer of energy starts from producers in a food chain. Transfer of energy starts from detritus /decomposing organic matter. More energy flows through this. Less amount of energy flows through this .Energy obtained from Sun Energy obtained from dead organic matter Major conduit of energy in aquatic system Major conduit of energy in terrestrial system
