Introduction to tundra food web:Tundra Food Web is  something that is so beautifully well- woven that it strikes a wonderful balance in Nature if man does not interfere!
Here we have a plant species being consumed by an herbivorous fish species, which is being eaten by a carnivorous fish species which is being devoured by yet another carnivorous fish species. Of course, this is a very simplistic way of looking at the eating relationships in almost any ecosystem.


A better attempt at that holistic examination of a community's trophic interactions would be a food web. If you can imagine something like this diagram, but including all of the dozens and dozens of species in a typical ecosystem, you can begin to get an appreciation of the overwhelming complication of the tasks that ecologists attempt to perform.
As mentioned above, food chains and food webs serve the purpose of allowing us to examine the specific, species-to-species relationships among the organisms in an ecosystem. Note that the arrows represent the transfer of energy and always point from the organism being eaten to the one that is doing the eating.
