carbon dioxide
the most important, the conversion of Carbon Di-oxide to Oxygen!
Yes photosynthesis stores energy and respiration releases energy
The conditions under which the earliest organisms evolved were hot and anaerobic.
The atmosphere, the ocean, and the terrestrial biosphere.Carbon can be found in the earths oceanic and continental crust in different types of stones as well as in the soil from the decay of organic matter.
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
Without life because when plants do photosynthesis, they produce oxygen.
It was like a cow in water, and a dove giving birth...
photosynthesis
It will remain as reductive atmosphere. Ther will be only gases like NH3, H2 , H2S. H2O. There would be no life
Photosynthesis
photosynthesis
Photosynthesis by plants
Photosynthesis converts carbon dioxide into oxygen. Therefore, much of the oxygen in our atmosphere is present due to photosynthesis.
Carbon dioxide
Green plants evolved adding oxygen to the atmosphere.

The correct name for a shooting star is a Meteorite. Before a meteorite enters the Earths atmosphere it is called a Meteoroid.
