The statement that best explains why cyanobacteria are classified as autotrophs is:

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

Cyanobacteria are considered autotrophs because they are capable of photosynthesis, using light energy to synthesize organic compounds from carbon dioxide, thereby producing their own food.
