Photosynthesis is the process where animal make there own food through the process of sunlight

Photosynthesis is the process used by plants, algae, and cyanobacteria to convert light energy into chemical energy, through a process that uses sunlight, water, and carbon dioxide. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water. Oxygen is released as a byproduct.
