Autotrophic nutrition is shown by all photosynthetic organisms.
Photosynthesis is a process in which carbon dioxide and water are converted into carbohydrates in the presence of sunlight and chlorophyll.
All the green plants show autotrophic nutrition, by which they produce starch and some proteins.
Carbohydrates are utilised for providing energy to the plants. The excess carbohydrates are stored in form of starch, which is a complex carbohydrate. It serves as the internal reserve energy to be used as and when required.
