The process of getting food that is required for nourishment and sustenance of the organism is termed as nutrition. Generally, there are two main modes of nutrition including autotrophic and heterotrophic.

Autotrophic Nutrition

The organisms who make their food on their own using sunlight or chemicals such modes of nutrition are known as autotrophic nutrition. For example, plants photosynthesize and are called photoautotrophs whereas few bacteria use chemicals to develop energy and are known as chemoautotrophs.

Heterotrophic Nutrition

For example, animals that eat plants as their food are known as herbivores whereas animals who eat other animals as their food are called carnivores.
