How have green plants and other organisms changed the composition of the Earths atmosphere?
Hugely. Before the evolution of the first organisms capable of photosynthesis around 3 billion years ago, the atmosphere of the early earth contained almost no Oxygen. By the conversion of Carbon Dioxide and Water into organic compounds and Oxygen through photosynthesis, cyanobacteria, and later algae and plants, have raised Oxygen levels to around 21% of the atmosphere today. Without this high level of Oxygen, the huge diversity of multi-cellular life depending on Oxygen for aerobic respiration would not exist.
What else can I help you with?
Earths early atmosphere was changed dramatically by the evolution of?
photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.
Which group of organisms is most responsible for changing the compisition of earths early atmosphere?
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
How has the earths atmosphere changed over millions of years?
The earth's atmosphere has changed significantly over millions of years due to various factors such as volcanic activity, changes in the Earth's orbit, and the evolution of living organisms. For example, early Earth had a different composition with high levels of carbon dioxide and little oxygen. Over time, the atmosphere changed to its current composition with nitrogen as the dominant gas and oxygen supporting life.
How has the earths atmosphere changed during the Precambrian time?
During the Precambrian time, the Earth's atmosphere lacked free oxygen, and the early atmosphere was likely composed of gases such as methane, ammonia, and carbon dioxide. Throughout the Precambrian, there were significant changes in atmospheric composition due to volcanic activity and the evolution of photosynthetic organisms that contributed oxygen to the atmosphere.
What caused a major change in the composition of Earths atmosphere?
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.

Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.

Earths atmosphere was first changed by?
photosynthesis
How does the composition of Earths atmosphere different from the composition of the atmosphere of the gas giants planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere

How did earths atmosphere change?
The Earth's atmosphere has changed over time due to various factors such as volcanic activity, changes in greenhouse gas concentrations, and natural variations in solar radiation. Human activities, such as the burning of fossil fuels and deforestation, have also significantly impacted the composition of the atmosphere, leading to an increase in greenhouse gas emissions and global warming.
When did the chemical composition of earths atmosphere reach that of today?
It reach when your mother had sucked your dads dick
