The process by which light energy is converted to chemical energy is called photosynthesis.

Here's a breakdown:

* Light energy: This is the energy from the sun.

* Chemical energy: This is stored in the bonds of molecules, like glucose, which is a type of sugar.

Photosynthesis is carried out by plants, algae, and some bacteria. They use sunlight, water, and carbon dioxide to create glucose and oxygen. This glucose is then used by the organism for energy or can be stored for later use.
