How does energy actually get into your body?
Ever wondered why you need to eat food in the first place? You can't just run on sunlight like your houseplants. That's because your body needs energy, and the original source for almost all of it is the sun. Plants are the real MVPs here: they grab sunlight using a green pigment called chlorophyll and stash that energy inside molecules of glucose. This process turns sunlight into chemical energy,the kind your cells can actually use.
When you eat a salad, a burger, or even a chocolate bar, you're basically borrowing energy that plants trapped from sunlight. The energy is stored in the bonds of molecules like glucose.
When you hear "chemical energy," think of it as energy packed away inside those molecules, waiting to be released when you need to move, think, or even just stay warm.
Plants that make their own food using sunlight are called producers. Without them, there'd be no energy entering the living world,no snacks, no meals, nothing powering your next sprint to the bus stop.
