Hello Student
Is that a question or just a statement?
Well! Yes! They are their own food by using sun light energy.
Certain of the examples are; Purple bacteria, Green sulphur bacteria etc.

Phototroph (redirect from Photoautotrophic)

capable of synthesizing their own food from inorganic substances using light as an energy source. Green plants and photosynthetic bacteria are photoautotrophs

Nutrition in Bacteria:

Autotrophic Bacteria –

Some bacteria can synthesize their food and hence they are autotrophic in their mode of nutrition. They may be photoautotrophs (eg. Spirillum) or chemoautotrophs (eg. Nitrobacter).

Photoautotrophic bacteria:

They use sunlight as their source of energy to synthesize food. But, unlike photosynthetic eukaryotic cells, they do not split water to obtain reducing power. So, oxygen is not evolved during bacterial photosynthesis. Depending on nature of hydrogen donor, these bacteria may be:

1. Photolithotrops:

In this bacteria, hydrogen donor is an inorganic substance. In green sulphur bacteria, (Chlorobium), hydrogen sulphide (H2S) is the hydrogen donor. The chlorophyll is bacterioviridin.

In purple sulphur bacteria (Chromatium), thiosulphate acts as hydrogen donor. The chlorophyll is bacteriochlorophyll.

2. Photo-organolithotrophs:

In this, the hydrogen donor is an organic acid or alcohol eg. Purple non-sulphur bacteria (eg. Rhodospirillum).
