what is food chain?
A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level..

☞Producers based : All sustainable food chains are producer based.
☞Energy : Producers obtain energy from sun. ...
☞Biogenetic Nutrients : Inorganic nutrients must keep on circulating with the help of decomposers.
Explain how energy flows through different trophic levels in a food chain?
The producers synthesise food by the process of photosynthesis. A part of the energy is stored within the plants. The remaining energy is utilised by the plants in their growth and development. This stored energy is transferred to the primary consumers when they feed on the producers.
