The Carbon Cycle

🧠 Remember it Carbon moves in a loop: photosynthesis takes CO₂ IN, respiration and combustion put CO₂ OUT. "Plants breathe it in, burning breathes it out."

🌏 In real life Every time a bus burns diesel or you light a gas stove, carbon locked in the fuel is released as CO₂ — the same CO₂ a nearby tree pulls back in to make its food.

📝 Quick notes Carbon is stored in the air (as CO₂), in living things, in fossil fuels and in the oceans. Photosynthesis removes CO₂ from the air and locks carbon into plant food. Respiration (by plants and animals) releases CO₂ back into the air. Decomposition and combustion (burning wood or fossil fuels) also release CO₂.

🎯 Test yourself Which process removes CO₂ from the atmosphere? Photosynthesis.
