Energy from the Sun

📚 Key Concepts

🔹 Solar Energy

The Sun is the main source of energy on Earth. All life depends directly or indirectly on solar energy.

Uses of Solar Energy:

1. Photosynthesis – Plants make food using sunlight
2. Water cycle – Sun causes evaporation
3. Drying – Clothes, food preservation
4. Solar panels – Generate electricity
5. Solar cookers – Cook food using solar heat

🔹 Energy Chain

Sun → Plants → Animals → Humans

• Plants capture solar energy through photosynthesis
• Animals eat plants and get energy
• Humans get energy from plants and animals
