Which of the following is a food chain in the food web shown in the figure above?
wel

The food chain that is shown in the food web could be any of the following:

  • tree → deer → mountain lion
  • grass → rabbit → mountain lion
  • grass → rabbit → hawk
  • grass → grasshopper → frog → snake → fox
  • grass → grasshopper → snake → hawk
  • grass → grasshopper → snake → fox → mountain lion
  • tree → caterpillar → robin → fox → mountain lion
<h3 /><h3>FURTHER EXPLANATION</h3>

A food chain shows a unidirectional feeding relationship among organisms in an ecosystem. The organisms occupy a certain "place" in the food chain called trophic level. Food chains may have several trophic levels which always begin with the producers.

  • Producers are organisms which make their own food. Plants are examples of producers.
  • The organisms the directly feed on the plants are called the primary consumers. They are either herbivores or omnivores.
  • The organisms that feed on the primary consumers directly are called secondary consumers. Those that feed on the secondary consumers are called tertiary consumers and quaternary consumers feed on tertiary consumers. These are either omnivores or carnivores.
  • The apex predator is the animal at the top of the food chain. It is preys on the organisms in the lower trophic levels but nothing preys on it.

A food web, on the other hand, is a series of food chains showing the interdependence of organisms in an ecosystem.
