A network of interconnecting food chains in a natural community of different organisms is called a food web.

Example of Food Web

  • Consider six food chains which are interconnected to form a food web. The food web begins with plants and ends with the top carnivore, the vulture.
  • In the first food chain, the plants are eaten by the grasshopper, and the grasshopper, in turn, is eaten by the vulture.

Plants → Grasshopper → Vulture

  • In the second food chain, the plants are eaten by the rabbit. The rabbit is then consumed by the vulture.

Plants → Rabbit → Vulture

  • In the third food chain, the plants are eaten by the rat. The rat is then eaten by the vulture.

Plants → Rat → Vulture

  • In the fourth food chain, the plants are eaten by the rat, the rat is eaten by the snake, and the snake, in turn, is eaten by the vulture.

Plants → Rat → Snake → Vulture

  • In the fifth food chain, the plants are eaten by the grasshopper, and the grasshopper, in turn, is eaten by the frog. The frog is eaten by the snake, and the snake is consumed by the vulture.

Plants → Grasshopper → Frog → Snake → Vulture

  • Finally, in the sixth food chain, the plants are eaten by small birds which in turn are eaten by the vulture.

Plants → Small birds → Vulture
