Bacteria have many important roles in nature except being responsible for

converting sunlight into usable chemical energy.

Bacteria are organisms and are prokaryotes and have some beneficial

uses e.g in decomposition as well as non-beneficial uses e.g pathogens for

illnesses.

Bacteria however don't convert sunlight into usable chemical energy as this

is done by the primary producers such as plants. This process is regarded as

photosynthesis in which plants convert light energy from the sun to

chemical energy needed by the consumers.
