Food chains
🌱 Definition
A food chain is a way of showing how energy and nutrients pass from one living thing to another through eating and being eaten.
🌍 Main Details
It always starts with producers (like plants) that make their own food using sunlight.
Then come consumers (animals that eat plants or other animals).
It ends with decomposers (like fungi and bacteria) that break down dead things.
Energy moves in one direction — from the sun → plants → animals.
Each step in a food chain is called a trophic level.
🐾 Examples
Grass → Grasshopper → Frog → Snake → Eagle
Leaves → Caterpillar → Bird → Cat
Algae → Small fish → Big fish → Shark
✨ Interesting Points
If one part of a food chain is removed, the whole chain can be affected.
Animals can be part of more than one food chain.
Many food chains connect together to form a food web.
The higher you go in the chain, the less energy is available.
🌟 Fun Fact
A lion may be a top predator, but when it dies, tiny decomposers like bacteria still eat it—so even the strongest animals become part of the food chain!
