Autotrophs are organisms that are capable of producing complex organic compounds from simple substances using either sunlight energy or chemical energy.
Autotrophs are called producers as they are the source of energy for most organisms in food chains.
The autotrophs that use sunlight energy to produce energy in form of complex organic compounds are known as photoautotrophs.
The autotrophs that use chemical energy to convert simple organic materials to complex organic energy containing substances are known as chemoautotrophs.
The main difference between photoautotrophs and chemoautotrophs is that photoautotrophs contain chlorophyll that helps them to trap the sunlight energy used in the process of photosynthesis.

In autotrophic mode of nutrition the food is manufactured by the organism itself in the presence of sunlight by taking in raw materials such as carbon dioxide or water from the surrounding All the green plants, blue green algae and autotrophic bacteria have autotrophic mode of nutrition. The organisms which can make their own food in the presence of sunlight by taking carbon dioxide and water from their surroundings are called autotrophs.
