Asked in Atmospheric Sciences
How did oxygen come into the atmosphere according to evolutionists?
Scientists agree that significant amounts of oxygen were first put into the atmosphere by cyanobacteria which used and still use a process called photosynthesis to convert carbon dioxide and water into sugar and oxygen. The sugar is then used to build cell walls and in the metabolism. When plants evolved, they too carried out photosynthesis, putting even more oxygen into the atmosphere. Prior to the evolution of cyanobacteria, the metabolisms of organism relied on anaerobic processes. ...
Asked in Evolution
How did cyanobacteria affect evolution process?
Cyanobacteria photosynthesised, which meant that they released oxygen. This was the key to the evolution of eukaryote cells that aerobically respired. From their evolution, the O2 levels in the atmosphere was able to increase; this is why we eventually evolved. ...

What process do cyanobacteria have in common with plants?
Cyanobacteria is blue- green algae. It , like plants uses the process of making cell wall. ...
Asked in Science, Earth Sciences
How did earth's atmosphere become so oxygen-rich?
The oxygen in Earth's atmosphere comes from plants and algae carrying out photosynthesis, in which energy from sunlight is used to convert water and carbon dioxide into sugar and oxygen The process started with cyanobacteria. ...
Asked in Biology, Photosynthesis
What is the function of the stomata in photosynthesis?
Photosynthesis is an essential life process carried out in plants, algae and cyanobacteria. Using raw materials from the environment, a plant uses light energy from the sun with water and carbon dioxide and creates food and energy. As a result, the plant is able to grow and fuel the atmosphere with oxygen. Because of photosynthesis, life exists on Earth. ...

What process has changed the percentages of nitrogen in the atmosphere?
Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration. ...
Asked in Biology
What is caused by cyanobacteria and leads to fish dying?
Large colonies of cyanobacteria produce cyanotoxins such as anatoxins and saxitoxin that are poisonous to animals. the name of the process is called algae bloom ...
Asked in Hydrology
What are Water vapors that rise from plants into the air?
Transpiration is a process in the Hydrological Cycle where moisture carried through plants changes into vapor and is released from leaves into the atmosphere. ...
What is the Major process by which CO2 is removed from the atmosphere?
Photosynthesis is a process that removes co2 from the atmosphere.
Asked in The Difference Between
What is the difference between archaebacteria and cyanobacteria?
Cyanobacteria gains energy through the sun, while archaebacteria gains energy through chemosynthesis (a process in which organisms gain energy through molecules such as sulfur)...
Asked in Oceans and Seas
How did cyanobacteria help form earths oceans and air?
Cyanobacteria help form Earth's oceans and air from doing its own natural process. Photosynthesis. Photosynthesis then distributed oxygen into the water and air. ...
Asked in Biology, Earth Sciences
What process do scientists think provided earth with an oxygen-rich atmosphere?
Scientists believe that stromatolites were responsible for providing an oxygen-rich atmosphere in precambrian times. Stromatolites are structures formed of sediment. The cyanobacteria that formed these structures were photoautotrophs that used sunlight, carbon dioxide and water to produce their food and a byproduct of oxygen. ...
Does the process of decay releases carbon dioxide into the atmosphere?
The process of decay releases carbon dioxide into the atmosphere
