Autotrophs, but not heterotrophs, can nourish themselves beginning with and other nutrients that are inorganic.
Explanation:
Unlike heterotrophs, autotrophs such as green plants, are able to synthesize their food (in form of sugar molecules) starting with inorganic molecules like atmospheric carbon dioxide, water in the presence of sunlight. 
This is commonly known as photosynthesis. The equation is shown below 
6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy 
 
        
             
        
        
        
Answer:
