What are autotrophs?

Autotrophs are living things that can make their own food using sunlight or other energy sources.

Imagine you're a plant sitting in the sun. You don’t need to go anywhere to get your snacks, you just make them right there, using the sunlight and some ingredients from the air and soil. That’s what autotrophs do! They’re like little food factories with sunlight as their power source.

Most autotrophs use a process called photosynthesis, which is like cooking in the sunlight. Think of it as a recipe:

• Sunlight (the heat and light from the sun)
• Carbon dioxide (a gas we breathe out)
• Water (from the soil or rain)

These ingredients get mixed together inside the autotroph, and poof, they make glucose, which is like food for them. This gives them energy to grow, stay healthy, and even help other creatures by being eaten.

Some autotrophs don’t use sunlight, they might live deep in the ocean or underground, using chemical reactions instead of the sun to create their food. But all of them are amazing at making their own snacks without needing to go shopping!
