They convert light energy into chemical energy to produce their own food.

Explanation: Autotrophs synthesize organic molecules from inorganic sources. Cyanobacteria perform photosynthesis, using light to make their own food (and also fix atmospheric nitrogen), so they are classified as autotrophs.
