Summary Introduction
Introduction:
Autotrophs are the organisms that make their own food by using sunlight, carbon dioxide and water by the process of photosynthesis. Photosynthesis is the process by which autotrophic organisms use sunlight energy to make sugar and oxygen gas from carbon dioxide and water.
