According to the type of nutrition, living organisms are divided into auto- and heterotrophs. What is their difference? What organisms are classified as autotrophs?

1) The main difference between autotrophs and heterotrophs is the chemical nature of the nutrients they need. Autotrophs synthesize organic substances from inorganic ones. Heterotrophs are not capable of such an independent synthesis: they require organic matter produced by other organisms.
2) Autotrophs include all green plants, cyanobacteria and many groups of bacteria, archaea from the halobacterial group, and chemotrophs.
