Without life because when plants do photosynthesis, they produce oxygen.
What else can I help you with?
How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
What effect does photosynthesis have on the amount of oxygen in the atmosphere?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
When organisms began using photosynthesis what gas was added to the atmosphere as a result?
Oxygen is one of the products of photosynthesis and is the gas that rose in abundance in the atmosphere due to the process of photosynthesis.
What was earth's atmosphere like before photosynthesis?
Before photosynthesis, Earth's atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. There was very little oxygen present. The emergence of photosynthetic organisms over billions of years dramatically altered the composition of the atmosphere to include more oxygen and less carbon dioxide.
What exchanges gases between the plant and the atmosphere during photosynthesis?
CO2 is taken in by the plants from the atmosphere and O2 is released during photosynthesis.
What was Earths atmosphere before photosynthesis?
It was like a cow in water, and a dove giving birth...
Earths atmosphere was first changed by?
photosynthesis
What gas was not found in earths early atmosphere but was produced by photosynthesis?
Carbon dioxide
What component of Earths atmosphere exists entirely as a result of photosynthesis?
Oxygen is the component of Earth's atmosphere that exists entirely as a result of photosynthesis. Plants and other photosynthetic organisms convert carbon dioxide into oxygen during the process of photosynthesis.
What is the name of a shooting star before it enters the earths atmosphere?
The correct name for a shooting star is a Meteorite. Before a meteorite enters the Earths atmosphere it is called a Meteoroid.
What component of the earths atmosphere exists as a result of photosynthesis?
Oxygen is the component of the Earth's atmosphere that exists as a result of photosynthesis. During photosynthesis, plants and other photosynthetic organisms release oxygen as a byproduct. This process helps to replenish and maintain the oxygen levels in the atmosphere, supporting aerobic life forms.
What process adds oxygen to earths atmosphere?
Photosynthesis
Which process producer most of the oxygen in earth's atmosphere?
The process that produces most of the oxygen in Earths atmosphere is photosynthesis. Plants use this process to create food.
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.
What was the earth's atmosphere like before photosynthesis?
Without life because when plants do photosynthesis, they produce oxygen.
How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
How do plants contribute to earths atmosphere?
Plants contribute to the Earth's atmosphere by releasing oxygen through the process of photosynthesis. This oxygen is essential for the survival of most living organisms, including humans. Additionally, plants help regulate the levels of carbon dioxide in the atmosphere by absorbing it during photosynthesis.
