Detailed explanation-1: -An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
Detailed explanation-2: -“Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.” The term “autotrophic” is formed by the combination of two terms, “auto” meaning self, and “trophic” meaning nutrition.
Detailed explanation-3: -Autotrophs are vital to all ecosystems because all organisms need organic molecules and only autotrophs can produce them from inorganic compounds. There are two basic types of autotrophs: photoautotrophs and chemoautotrophs.
