Autotrophs: Are organisms that can

Autotrophs are organisms that can make their own food using inorganic materials. They either use water, carbon dioxide, and energy from sunlight or use a variety of chemicals to prepare food. Since autotrophs produce their own food, they are also called primary producers. Autotrophs and Heterotrophs Autotrophs obtain energy and nutrients by harnessing sunlight through photosynthesis (photoautotrophs) or, more rarely, obtain chemical energy through oxidation (chemoautotrophs) to make organic substances from inorganic ones. What are examples of autotrophs and how do they produce their own food? Learn about different types of autotrophs in this guide by SSI Aeration, Inc.
