A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. Trophic levels include different categories of organisms such as producers, consumers, and decomposers. Producers are the basic trophic level while top predators are the peak level.

Food Chains And Food Webs Worksheet

The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a food "web". Ecological communities with higher biodiversity form more complex trophic paths.

Food web , on the other hand, is defined as the convoluted or complicated pathway of an ecosystem consist of numerous food chains of the different trophic level, through which the energy flow. Food chains, food web, are the part of the ecosystem which can be described as the community of the smallest microorganisms, plants to the higher animals that feed, live, reproduce, interact and die in the same area or environment. All ecosystem have feeding hierarchy which includes the sun energy source , producer, consumer, and decomposer. But in an ecosystem, it is impossible to have a single food chain. To survive, the organisms feed on the different trophic level. So in the food web, different food chains are linked together as well crisscross each other to form a complex network. The food web enhances the competitiveness and adaptability among organisms, but it is not seen in the food chain.
