Autotrophic organisms, such as plants and some bacteria, synthesize their own organic compounds for energy and carbon requirements. The primary process by which most autotrophs achieve this is photosynthesis, using light energy to convert carbon dioxide and water into glucose (a carbohydrate) and oxygen.
Autotrophs obtain their carbon and energy through processes like photosynthesis or chemosynthesis.
