Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
<h3><em>Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.</em></h3>
In order to move you need oxygen and water to form the energy to function. The frog is basically drinking water and doesn’t need to move while doing so. You only need to breath to allow your body to move.
