• Foodchain:
  • ​The sequence of living organisms in a community in which one organism consumes another organism to transfer food energy is called a food chain.
  • In simple words, a list of organisms showing 'who eats whom' is called the food chain.
  • The food can be transferred from one organism to the other through the food chain.
  • All food chains begin with green plants which are the source of all food.
  • It represents a unidirectional transfer of energy.
  • Example: eagle → snake → frog → insects → grass
  • Each step in the food chain is called a trophic level.
  • A food chain starts with producers and ends with top carnivores.
• eagle → snake → frog → insects → grass
  • Here grass is eaten by insects, insects are eaten by a frog, a frog is then eaten by a snake finally, a snake is eaten by an eagle.
  • This completes a food chain.
