Expert Answer:

You should draw figure 15.4 given in your NCERT book.

The things that become clear from it are:

The flow of energy is unidirectional. The energy that is captured by the autotrophs does not revert back to the solar input and the energy which passes to the herbivores does not come back to autotrophs. As it moves progressively through the various trophic levels, it is no longer available to the previous level.

Another aspect of food chain is how unknowingly some harmful chemicals enter our bodies through the food chain.
