how food chain is different from food webs

Food Webs - In nature, the food and feeding relationships of plants and animals are rarely as simple as the examples of food chains described above, because many animals eat more than one kind of food. On this account, different ..

Food Web - In nature, food chain relationships are not isolated. They are very complex, as one organism may form the food source of many organisms. Thus, instead of a simple linear food chain, there is a web like struct..

The different steps or levels in a food chain form different trophic levels. The illustration below is self-explanatory. This is the ecosystem that can exist on land. Trophic levels Thus a food chain of four levels is built up where green ..

a) These are directly dependent upon solar radiations as the primary source of energy and the producers (green plants) synthesize their plant biomass by the process of photosynthesis. Producers form the first trophic level. b) Herbivores or primary consumers eat upon the producers and form the seco..

The study of food chains helps in understanding some of the important aspects of the ecosystem in particular and environment in general. The food relationship among the different organisms in an ecosystem The food chains are the living..
