2) chemoheterotrophs
O 3) chemolithotrophs.
O 4) photoautotrophs
5) chemoautotrophs.
Organisms which use light as an energy source and carbon dioxide as a source of carbon are called and organisms which require preformed organic molecules as a source of carbon and
energy are called
1.photoheterotroph:chemoautotroph
2. chemoautotrophs, chemoheterotrophs
