A food chain shows a direct transfer of energy between organisms. In addition to a … Trophic levels and efficiency of energy transfer. Hetero (other) + Troph (feeding) = Other feeding These organisms must feed on other organisms. Both food chains and food webs are similar to each other, but they are not the same. Test your knowledge of food chains and food webs! To approach the notions of predator and prey. The major species in each lake are briefly described, along with a diagram summarizing the ecosystem energy flow (who eats or is eaten by whom!). We start to see the importance of the balance set by the food webs when we see the consequences of anthropological interferences in those food webs. If one type of prey becomes scarce, a predator might switch to consuming more of another species it eats. All ecosystem have feeding hierarchy which includes the sun (energy source), producer, consumer, and decomposer. But in an ecosystem, it is impossible … As every organism can feed on multiple things, a food web is a much more realistic and simplified method of transferring energy in an ecosystem. Simple food chain is very rare. In an ecosystem, the various food chains are inter-connected with each other to form a net work called Food Web.
