"On the Carbon Source of Autotrophs"

Autotrophs use inorganic carbon as their carbon source. Husband autotrophs, unlike heterotrophs, can ingest inorganic things on their own to form the organic matter they need. Its ecological position is crucial and it is the foundation of various biological chains.

Autotrophs rely more on light energy or chemical energy to fix carbon. For example, photosynthetic autotrophs use the power of light to attract carbon dioxide and water to form sugar and oxygen through a series of biochemical changes. Among them, carbon dioxide is the source of carbon and is the foundation for the synthesis of organic carbides.

Another example is a chemo-autotrophic person. Although they do not use light as energy, they use the energy released by the oxidation of inorganic matter, and also take carbon dioxide as a carbon source to produce their own biomass.

In summary, autotrophs rely on inorganic carbon sources to build the cornerstone of life, and in the ecological cycle, they take on the heavy responsibility of material and energy conversion, which is fundamental to the survival and reproduction of all species.
