Organisms that produce their own food are called autotrophs.

Here's a breakdown:

* Autotrophs: These organisms use energy from the environment to create their own food. The most common form of autotrophy is photosynthesis, where plants use sunlight to convert carbon dioxide and water into glucose (a type of sugar).

* Heterotrophs: These organisms obtain their food by consuming other organisms. This includes animals, fungi, and most bacteria.
