The food web also helps to determine the various ways in which energy flows and it usually starts from the producers which are the plants as a result of their photosynthetic ability which involves the conversion of solar energy to chemical energy.

There are various organisms in the ecosystem and the food web helps to provide a better understanding of their feeding habits and impact various factors will result in.
