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.

Detailed explanation-2: -Chemoautotrophs. Chemoautotrophs are those that make organic compounds as food by chemosynthesis. They use chemical energy to produce carbohydrates instead of light energy as photoautotrophs do. They utilize inorganic compounds such as hydrogen sulfide, sulfur, ammonium, and ferrous iron as reducing agents.

Detailed explanation-3: -Autotrophs are organisms that can produce their own food, using materials from inorganic sources. The word “autotroph” comes from the root words “auto” for “self” and “troph” for “food.” An autotroph is an organism that feeds itself, without the assistance of any other organisms.

Detailed explanation-4: -An autotroph is defined as any organism that uses an inorganic source of carbon and makes its own organic matter as opposed to a heterotroph, which uses pre-made organic matter.

Detailed explanation-5: -An autotroph is an organism able to make its own food. Autotrophic organisms convert inorganic molecules into organic compounds. Autotrophs are referred to as primary producers, and they occupy the ecological niche at the base of all food chains.
