Here's a breakdown:

* Autotrophs are organisms that can produce their own food from inorganic sources. They do this through a process called photosynthesis, where they use sunlight, water, and carbon dioxide to create energy in the form of glucose.

* Plants are a prime example of autotrophs. They have chlorophyll, a green pigment that absorbs light energy for photosynthesis.

Other examples of autotrophs include algae and some bacteria.
