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: -Autotrophs rely on either light or chemical energy to turn CO2 into organic carbon molecules. Photoautotrophs are photosynthesizing organisms such as algae and higher plants that use light for this process. Heterotrophs, in contrast, obtain their chemical energy from preexisting organic molecules.

Detailed explanation-3: -Chemoautotrophs are the organisms that use carbon dioxide as their carbon source in nutrition, and chemoheterotrophs are dependent on organic compounds to extract their energy. Chemoautotrophs derive their energy from carbon dioxide and inorganic compounds.

Detailed explanation-4: -An autotroph is an organism that can produce its own food using inorganic substances. In contrast, heterotrophs are organisms that cannot produce their own nutrients and require consumption of other organisms to live.
