Question

Plant, Tiger, Rabbit, Fox, Eagle.
Did you find any connection between the above list of organisms? If we remove rabbits from the list what will happen?

Answer 1

Hint: This is the sequential form of organisms telling who eats whom. It helps in getting an idea of the nutrients and the energy flow from one to another trophic level. It is the relationship showing the consumption of an organism linearly eating another organism to attain energy for survival.

Complete answer:
The food chain is the linear network of links present in the food web which starts from the green plants (producers) and lasts at the predators (consumers). It is the series of the flow of energy and nutrients in an ecosystem. A food chain indicates the relationship between the organism by their eating habits. The various levels of food chains represent various trophic levels. Plant, tiger, rabbit, fox, and eagle are various organisms in a food chain. If rabbits are removed from the food chain then while of them will get disturbed and break and energy will not be able to transfer to the next level.
-An organic phenomenon may be a linear sequence of organisms through which nutrients and energy pass together.
-The producers lie at the bottom of the food chain. The autotrophs generally include photosynthetic organisms like algae, cyanobacteria, and plants that come under the primary producers.
-The primary consumers include those organisms that eat producers that include herbivores, algae eaters, plant-eaters, or bacteria eaters.
-The secondary consumers include those organisms that eat first consumers. Secondary consumers include carnivores called meat-eaters.
-Those organisms are called tertiary consumers that eat secondary consumers that include carnivore-eating carnivores, like eagles or big shot.
-Some food chains also constitute additional levels, like quaternary consumers that are the carnivores that eat tertiary consumers. The apex consumers are those organisms that are present at the very top of the food chain.
-The interconnected network of the food chain constitutes food webs that help in connecting the various organisms and transfers the energy and nutrients.
-When the energy moves in between the trophic levels then 10% of the energy gets wasted resulting in the wasteful of the productivity. This inefficiency of the food chains will lower the limits and length of food chains.

Note:
The food chain was first introduced in the tenth century by Al-Jahiz who was an Arab scientist and philosopher. It was later published in 1927 and was later extended by Charles Elton. Charles Elton also introduced the concept of the food web.
