Food web is a network of several food chains present in an ecosystem where they get interconnected at various trophic levels. It makes each food available to several populations.

In an ecosystem, various food chains are linked together and intersect each other to form a complex network called a food web. The food web consists of a few interconnected food chains through which food energy is passed in the ecosystem. Members of higher trophic level can feed on several alternative organisms of the lower trophic level.
