Food Chain And Food Web Class 10. The food chain can be said as the straight and single pathway for the flow of energy in an ecosystem, through different species of organisms.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 chain is a linear sequence of organisms which starts from producer organisms and ends with decomposer species.
Due to this, many trophic levels get interconnected, and the food chain fails to showcase the flow of energy in the right way. Links higher up in the food chain rely on the lower links. A food chain is a series of organisms where all the organismsare dependent on next organism as a source of food.
Each step or division in food chain which is characterized by a particular method of obtaining food is called trophic level.
Out of the energy consumed by an organism at a particular trophic level, 90% is utilised for its own need and rest 10% is left for the organism of the next trophic level. A food chain is the path by which energy passes from one living thing to another. When various food chains link together to form a network, it refers to the food web.
