Question

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

Answer 1

Mountain lion feeds on deer which further feeds on tree.

Hawk feeds on rabbit that feeds on grass.

Mountain lion feeds on fox that feeds on snake which feeds on grasshopper which further feeds on grass.

Further Explanation:

Food chain indicates the sequence in which the matter and the energy is transferred in the form of food from an organism to another one. Food chain forms the local network and thereby forms food web. Food web takes into account the fact that most organisms consumes more than one kinds of plants or animal.

The primary producer in the food chain is the plant or phytoplanktons that are able to photosynthesize.

The characteristic feature of the food chain is:

• Primary producers are present at its base. They are mostly autotrophs.

• The organisms that feed over primary producer are known as primary consumer. Primary consumers are the herbivores.

• Secondary consumer feeds on primary consumer and this trophic level can go till quaternary consumer.

The trophic levels in the food chain do not go beyond the four or five trophic because at every level the energy is lost in the form of heat.

Answer 2

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

FURTHER EXPLANATION

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.
