Answer:
A food chain is very simple, while a food web is very complex and consists of a number of food chains. In a food chain, each organism has only one consumer or producer. For example, a deer eats grass and a tiger eat the deer. In a food web, a consumer may eat a number of different producers.A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.A food chain only follows just one path as animals find food. A food web shows the many different paths plants and animals are connected. A food web is several food chains connected together. Food chains always begin with a plant and end with an animal.Webs are more realistic than food chains, in that food chains show just a single feeding pattern. Each organism has a single role in the ecosystem. In reality, animals can have more than one food source, and the relationships between different organisms are much more complex.
