Introduction of Food Chain

What is a food chain? Imagine eating your favorite meal. Afterward, you feel energized and ready to do almost anything! The food you eat gives you the energy to play, grow, and do all the things you need to do throughout the day.

All living things need food, and food gives them energy. A food chain shows how living things get the food they need.

Let us discuss this in detail.


The flow of energy from one living thing to another living thing is called a food chain.

Depending on how living things get their energy, they are either producers, consumers, or decomposers.



Producers make their energy from sunlight, air, and soil. Examples of producers include plants and plants like organisms such as algae. 


The organisms that eat producers are referred to as consumers, and they cannot produce energy on their own and must eat other living things. Consumers include animals because they eat other plants and animals. 


They break down and eat dead plants and animals—for example, mushrooms, earthworms, and bacteria.

Example of producers, consumers, and decomposers in a food chain

There are Four Different Types of Consumers

Herbivore – is an animal that only eats plants.

Carnivore – an animal that only eats other animals.


Omnivore – an animal that eats both plants and animals.

Scavengers – an animal that eats dead animals.

See the example of a food chain given in the below image.

The Sun is the beginning of every food chain. Without the Sun, plants could not grow, and there would be no food for animals.

A food chain usually shows a line of animals that eat each other and is a never-ending cycle that repeats over and over.

A food chain usually starts with a plant and ends with an animal.

The energy passes from one animal to another as they eat plants or one another.

Here is another example of a food chain showing how energy moves from the Sun through living things.

The grass gets its energy from the Sun, the rabbit gets its energy from the grass, and the fox gets its energy from the rabbit.
