Which of the following organisms have a mode of nutrition that is not heterotrophic?

Autotrophic nutrition is a mode of nutrition in which organisms synthesize organic substances from inorganic substances such as carbon dioxide and water. Organisms that obtain their food by this method are called autotrophs.

Plants are autotrophic organisms. 

Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. Bacteria, fungi, yeast, cows, dogs, and humans are all heterotrophs. They all depend on plants and other animals for their food.
