Step-by-step explanation:

Food chains are the feeding relationships that exist between living things in an ecosystem. Through food chain analysis, it is possible to observe how nutrients and energy flow among living beings living in that region. Unlike a food web, the chain has a unidirectional flow. Here's an example:

• Plant → Butterfly → Frog → Snake

The food web better represents the feeding relationships that exist in an ecosystem. It can be defined in a simplified way as the various food chains of an ecosystem. Thus, the web does not have a unidirectional flow, like the food chain, because it shows that the same organism can have different eating habits and, consequently, occupy different trophic levels.
