Detailed Solution

Concept: The food chain is the linkage and interdependence of animals living in an ecosystem upon each other for food. There are different trophic levels present in the food chain that denotes the steps of how the food chain proceeds.
The food chain is a linear network of links in a food web that starts from producer organisms and ends at an apex predator species, detritivores, or decomposer species. A food chain also shows how the organisms are related to each other through the food they eat. Every level of a food chain represents a different trophic level. At every trophic level, there is the transfer of 10% energy. At the base of every food chain, producers are present, which are eaten by herbivorous, then flesh-eating organisms.
