What is the original source of energy for a sweet potato?

The original source of energy for a sweet potato, like all plants, is the sun.

Here's how it works:

* Photosynthesis: Sweet potatoes, like all plants, perform photosynthesis. This process uses sunlight, water, and carbon dioxide to create sugars (glucose) and oxygen. The sugars are the plant's primary source of energy.

* Energy storage: Sweet potatoes store the sugars they create during photosynthesis in the form of starch. This starch is what we consume and our bodies then break down into glucose for energy.

So, the sun's energy is ultimately converted into the energy we get from eating a sweet potato.
