Thus, we have a complex network of interconnected food chains called a food web.
For example, a snake might feed on a mouse, a lizard, or a frog.
Food Chain is a feeding hierarchy in which organisms in an ecosystem are grouped into nutritional (trophic) levels and are shown in a succession to represent the flow of food energy and the feeding relationship between them.
The directional flow of food energy from one organism to another is graphically represented by arrows.
