Q: Which of the following is grazing food chain?
  • A. Dead animal→ Maggots→ Frog→ Snake
  • B. Grass→ Rabbit→ Fox
  • C. Trees → Fruits eating birds →Lice and bugs
  • D. No option is correct
Correct Answer: Option B - A food chain explains which organism eats another organism in the environment. There are two types of food chain i.e. (i) Detritus food chain– This food chain includes different species of organisms and plants like algae, bacteria, fungi insect etc. This food chain begins with dead organic material. The food energy passes into decomposer and detritivores, which are further eaten by smaller organism like carnivores. (ii) Grazing food chain – This food chain is a type of food chain that start with green plants, passes through herbivores and then to carnivores. In a grazing food chain energy in the lowest trophic level and is acquired from photosynthesis. Example of grazing food chain is- Grass → Rabbit → Fox
