Which two domains do the prokaryotes belong?

A) Archaea and Cyanobacteria
B) Bacteria and Cyanobacteria
C) photosynthetic bacteria and chemosynthetic bacteria
D) Archaea and Bacteria
E) autotrophs and heterotrophs

Photosynthetic Bacteria

Bacteria capable of photosynthesis, a process that converts light energy into chemical energy, thereby producing oxygen as a by-product, crucial for earth's oxygen supply.

Chemosynthetic Bacteria

Microorganisms that obtain energy by converting inorganic molecules to organic matter, independent of sunlight.

Autotrophs

Organisms that produce their own food from inorganic substances, like carbon dioxide and water, typically through photosynthesis.
