The basic structure of geoporphyrins, especially those with an exocyclic ring in the southern part of the molecule, is strongly suggestive of origin from chlorophylls and bacteriochlorophylls, which are major photosynthetic pigments of photoautotrophs. Therefore, organic geochemists have long regarded geoporphyrins as excellent molecular markers for photosynthetic organisms in the surface water.
They're photoautotrophs: they make their own food by capturing energy directly from sunlight.

Being photoautotrophs, they utilize C[O.sub.2] for photosynthesis which can be useful in C[O.sub.2] sequestration [1,10].

These include diverse microborings attributable to green algae and cyanobacteria; these photoautotrophs indicate a relatively strong light source, suggestive of shallow euphotic zone III (e.g., Vogel et al.

The mixotrophic microalgae used in this study were Chlorella, Scenedesmus sp., Cosmarium sp., and facultative heterotrophs (centric and pinnate diatoms) along with few photoautotrophs (Cyclotella and Oedogonium) and obligate photoautotrophs (P.
Oxygenic prokaryotic photoautotrophs (Cyanobacteria) were estimated to constitute about 10% of the total ocean marine picoplankton in the upper 200 m [1].
This chart can then be examined from the point of view of biogenesis and also can be compared with the anabolic features of oxidative heterotrophs and photoautotrophs to look for robust universal features of metabolism that have persisted for several billion years.
"These data strongly suggest that oxygenic photoautotrophs flourished in the photic zone of the 3.46 billion-year-old oceans and supplied molecular oxygen to the deep water," said the researchers.
