The energy conversion that takes place when a plant makes food is light energy to chemical energy. Here's a breakdown:

* Light energy: Plants absorb light energy from the sun.

* Chemical energy: Plants use this light energy to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. This process is called photosynthesis. The glucose stores chemical energy that the plant can use for growth and other processes.

So, in simpler terms, plants take light energy from the sun and turn it into stored chemical energy in the form of glucose, which they use as food.
