∙ 7y agoAerobic respiration evolved as oxygen levels increased in Earth's atmosphere. This process allows living organisms to efficiently extract energy from food by using oxygen to break down glucose molecules and produce ATP. As oxygen became more abundant, organisms that could perform aerobic respiration gained a significant evolutionary advantage.
Photosynthesis played a crucial role in the evolution of Earth's atmosphere by producing oxygen as a byproduct. This process greatly increased the amount of oxygen in the atmosphere, making it possible for aerobic organisms to thrive and leading to the development of more complex life forms. The rise of photosynthetic organisms also contributed to the stabilization of Earth's climate over time.
True. Scientists believe that the first life forms on Earth likely arose from nonliving materials through a process known as abiogenesis. This theory suggests that simple organic molecules gradually evolved into more complex structures that eventually led to the development of life.
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
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.
Earth's atmosphere got its free oxygen through the process of photosynthesis by early photosynthetic organisms, such as cyanobacteria and algae. These organisms used sunlight to convert carbon dioxide and water into oxygen and glucose, releasing oxygen as a byproduct. Over time, this led to the buildup of oxygen in the atmosphere, fundamentally changing the composition of Earth's air.
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
it has increased vision since its out of earths atmosphere
Green plants evolved adding oxygen to the atmosphere.
The process that produces most of the oxygen in Earths atmosphere is photosynthesis. Plants use this process to create food.
The early Earth's atmosphere lacked oxygen because oxygen was not initially produced by photosynthetic organisms. Instead, the atmosphere consisted primarily of gases emitted from volcanic activity, such as water vapor, carbon dioxide, and nitrogen. Oxygen levels increased over time as photosynthetic bacteria and plants evolved.

It will remain as reductive atmosphere. Ther will be only gases like NH3, H2 , H2S. H2O. There would be no life
Almost no oxygen, lots of CO2, still mostly nitrogen.
