Photosynthetic bacteria produced oxygen, and as they continued to colonize the earth they produced more oxygen. Eventually all the oxygen sinks became saturated, and this resulted in the Great Oxygenation Event (GOE). Aerobic organisms would late evolve and utilize the free oxygen.

What element upon which most modern organisms depend was missing from earth's early atmosphere?
Oxygen was the element missing from Earth's early atmosphere, which eventually accumulated due to early photosynthetic organisms. This change in the atmosphere allowed for the evolution of organisms that rely on oxygen for respiration.
What are the four major functions of photosynthesis?
The four major functions of photosynthesis are: Production of Oxygen: Photosynthesis generates oxygen as a byproduct, which is essential for the survival of aerobic organisms. Conversion of Light Energy: It transforms solar energy into chemical energy stored in glucose, providing energy for plants and, indirectly, for other organisms in the food chain. Carbon Dioxide Utilization: Photosynthesis absorbs carbon dioxide from the atmosphere, helping to regulate atmospheric CO2 levels and mitigate climate change. Nutrient Production: It produces organic compounds that serve as vital nutrients for plants and other organisms, forming the basis of the ecosystem's energy flow.
What does the sun change into during photosynthesis?
During photosynthesis, the sun's energy is converted into chemical energy stored in molecules like glucose by green plants and some other organisms. The sun itself does not physically change during this process but provides the energy needed for photosynthesis to occur.
How do simple plants change the Earth's atmosphere?
Simple plants, through the process of photosynthesis, take in carbon dioxide from the atmosphere and release oxygen. This process helps to regulate the levels of oxygen and carbon dioxide in the atmosphere. Plants also play a role in sequestering carbon, which can help mitigate the effects of climate change by reducing the amount of greenhouse gases in the atmosphere.
How did the earth change when organism began using photosynthesis to make food?
When organisms began using photosynthesis to make food, the Earth's atmosphere underwent a significant transformation. This process released oxygen as a byproduct, gradually increasing atmospheric oxygen levels, which enabled the evolution of aerobic organisms and diverse life forms. Additionally, photosynthesis played a crucial role in sequestering carbon dioxide, helping to regulate the planet's climate and paving the way for the development of complex ecosystems. Overall, it marked a pivotal shift in Earth's biogeochemical cycles and the dynamics of life.
How do tsunamis change the earths atmosphere?
cuz they can
What is true about earths atmosphere?
it will always change
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.
What change in Earths atmosphere allowed organisms to live on land?
The development of an ozone layer in Earth's atmosphere allowed organisms to move onto land. The ozone layer absorbs the sun's harmful ultraviolet radiation, providing protection for early land-dwelling organisms. This helped pave the way for the colonization of land by plants and animals.
Which major physical change could be attributed to photosynthesis?
Photosynthesis drastically increased the oxygen content of the atmosphere.
What helped change the earth's atmosphere after it was formed?
The earths atmophere came from your mom!
What was the biggest change in the earths atmosphere between the precambrian and the paleozoic eras?
The origin of free oxygen
As life began to populate earths surface what change was seen in the atmosphere?
more oxygen was consumed
What changes occurred in atmosphere as a result of photosynthesis?
The atmosphere was changed from being a reducing one to an oxidizing one. Then, the most important change was regarding the relative concentration of molecular oxygen, which is thought to have incremented a thousand times. Concomitantly the ozone layer also formed.
What element upon which most modern organisms depend was missing from earth's early atmosphere?
Oxygen was the element missing from Earth's early atmosphere, which eventually accumulated due to early photosynthetic organisms. This change in the atmosphere allowed for the evolution of organisms that rely on oxygen for respiration.
How has the earths atmosphere changed?
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.
Organisms that change the energy in sunlight into food are called?
Organisms that change the energy in sunlight into food are called autotrophs. They are able to perform photosynthesis, a process in which they use the energy from sunlight to convert carbon dioxide and water into organic compounds like glucose. This ability to produce their own food is essential for the survival of many living organisms.
