Cyanobacteria.
Cyanobacteria are among the earliest forms of life and are thought to have evolved approximately 2.5 billion years ago. These bacteria are thought to have changed the atmosphere of the planet via nitrogen fixation. The first dinosaurs evolved approximately 250 million years ago during the late Triassic.

Is anabaena free living?
Anabaena is a type of cyanobacteria that can exist as free-living organisms in aquatic environments. They can also form symbiotic relationships with fungi or plants, notably in the case of nitrogen-fixing cyanobacteria in symbiosis with certain plants.
What eon did they exist?
The dinosaurs existed during the Mesozoic Era within the Phanerozoic Eon.
What organisms are the first to photosynthesize?
Scientists believe the first photosynthetic organisms may have been cyanobacteria. This is believed because the biochemical pathways in the unicellular cyanobacteria.
Which gas was first produced on earth by cyanobacteria?
Cyanobacteria also called as blue green algae. They are the photosynthetic prokaryotes. They are found in both marine and freshwater. They are probably the most numerous taxon to have ever existed on earth and the first organism know to have produced oxygen.
Are cyanobacteria consumers?
Cyanobacteria utilize the energy of sunlight to drive photosynthesis, a process where the energy of light is used to split water molecules into oxygen, protons, and electrons. While most of the high-energy electrons derived from water are utilized by the cyanobacterial cells for their own needs, a fraction of these electrons are donated to the external environment via electrogenic activity. Cyanobacterial electrogenic activity is an important microbiological conduit of solar energy into the biosphere.
In which era did dinosaurs begin to exist?

What life form evolved during the Paleozoic era cyanobacteria humans reptiles or dinosaurs?
During the Paleozoic era, cyanobacteria evolved and thrived, playing a crucial role in the Earth's early ecosystems by contributing to oxygen production through photosynthesis. While reptiles and dinosaurs appeared later, during the Mesozoic era, cyanobacteria were among the earliest life forms to exist on Earth, significantly influencing the planet's atmosphere and biological diversity. Humans, on the other hand, evolved much later, during the Cenozoic era.
How are dragons and dinosaurs different?
