Food web definition a series of organisms related by predator prey and consumer resource interactions.
What is a food web in biology. How food chains and food webs represent the flow of energy and matter. If youre behind a web filter. Food web is a network of interconnected food chains showing the energy flow through part of an ecosystem.

From the food chain we get to know how organisms are connected with each other. Food chain is a linear sequence of organisms which starts from producer organisms and ends with decomposer species. Food web is a connection of multiple food chains.
These are a more accurate way of showing feeding relationships than food chains because most animals have more than one food source.
