Here's how it works:

* Photosynthesis: Plants use sunlight, water, and CO2 to create their own food (glucose) and release oxygen as a byproduct. This process is called photosynthesis.

* Carbon Storage: The carbon from CO2 is incorporated into the plant's tissues (leaves, stems, roots).

* Carbon Sink: Plants act as a carbon sink, meaning they absorb more carbon than they release.

This process is crucial for the Earth's climate, as it helps regulate the amount of CO2 in the atmosphere.
