What is a food chain?

A food chain shows who eats whom. It always starts with a green plant, because only plants can make their own food using sunlight. The arrow → means “is eaten by”.

🌿 Grass→🦌 Deer→🐅 Tiger

🌿 Grass→🦗 Grasshopper→🐸 Frog→🐍 Snake→🦅 Eagle

🌾 Grains→🐀 Rat→🐍 Snake→🦅 Eagle

🍃 Leaves→🐛 Caterpillar→🐦 Sparrow→🐈 Cat

🌿 Grass→🐇 Rabbit→🦊 Fox

Who	What they do	Examples
Producers उत्पादक	Make their own food from sunlight, water and air	Grass, trees, wheat, water plants
Herbivores शाकाहारी	Eat only plants	Cow, deer, goat, rabbit, caterpillar
Carnivores मांसाहारी	Eat other animals	Tiger, lion, snake, eagle, frog
Omnivores सर्वाहारी	Eat plants and animals	Human, crow, bear, hen
Decomposers अपघटक	Break down dead plants and animals, return nutrients to the soil	Mushrooms (fungi), bacteria

All the energy in a food chain first comes from the Sun. Many food chains joined together make a food web. If one animal disappears, the whole chain is upset — with no snakes, rats would multiply and eat the farmer's grain.

Follows NCERT/EVS Class 4–7 (food chains, herbivores, carnivores, omnivores).
