A food web creator is a tool used to construct a food web, which is a map that illustrates the feeding relationship among all animals in an ecosystem. Species are connected by lines and arrows called "links," and they are sometimes referred to as "nodes."
Food webs differ from food chains in that while a food chain shows the linear relationships of feeding among species, a food web illustrates interconnected feeding relationships among organisms. Ecologist Charles Elton proposed the concept of a food web in 1927, which he then called the food cycle. He used it to describe the relationship between herbivores and carnivores and to explain how each group obtained its energy.
