Concept:In an ecosystem, many food chains link together to form a complex network called a food web.Explanation:A food chain shows a single path of energy transfer from producers to consumers. But in nature, each organism is part of many feeding relationships. For example, a plant is eaten by several herbivores, and each herbivore is eaten by multiple predators. These overlapping chains create a web-like structure. This interconnected group of food chains is called a food web. It allows energy to flow in multiple directions and makes the ecosystem more stable.
