Answer :
Organisms that are able to make organic molecules from inorganic sources, such as carbon dioxide and water, are called autotrophs.
In the field of science, autotrophs can be described as organisms that have the ability to produce their own food. These organisms usually use inorganic sources and derive their energy from them by converting them into organic sources.
The majorly known autotrophs are plants and cyanobacteria. These organisms have the ability to convert inorganic substances into organic substances through the process of photosynthesis. In the process of photosynthesis, carbon dioxide and water are used for making glucose and oxygen in the presence of light energy.
