A food web is a complex network of interconnected food chains that shows how different organisms in an ecosystem are related through their eating habits. It illustrates who eats whom, highlighting the flow of energy and nutrients from one organism to another. For example, plants are eaten by herbivores, which in turn are consumed by carnivores. In a food web, each organism plays a specific role, whether as a producer, consumer, or decomposer. This interconnectedness helps maintain balance in the ecosystem, as the removal or addition of one species can impact many others. Understanding food webs is essential for studying ecology and protecting biodiversity.
