Question

Describe food chain with the help of an example.

Answer 1

Answer:

The sequential process of eating and being eaten is called a food chain.

Grass → Grasshopper → Snake → Hawk → Fungi

All food chains begin with green plants or producers. Thus, the plants or producers constitute the first trophic level. Example: Grass

The herbivores or primary consumers that feed on plants constitute the second trophic level. Example: Grasshopper

The herbivores are next fed upon by the carnivores or secondary consumers. They constitute the third trophic level. Example: Snake

Finally, the large carnivores, also called the top carnivores or tertiary consumers, form the fourth trophic level. Example: Hawk

The large carnivores die and form the feed of decomposers. The decomposers feed on these dead animals and plants. Example: Fungi

There is a transfer of food from one organism to the other forming a chain.
