Is photosynthesis the reason the atmosphere is rich in oxygen gas?

No, Photosynthesis is where plants turn sunlight into food, the plants respiration (breathing) is why there is so much oxygen, as it converts the carbon dioxide we breathe out into oxygen.

What changed your formerly poisonous atmosphere into an oxygen rich atmosphere?
well, the first ice age is when blocks of ice and rocks release oxygen which helps us breathe
What planet has oxygon rich atmosphere?
Earth. It's the only planet with significant amounts of oxygen in the atmosphere, making up about 21%.
Because they trap oxygen from the atmosphere in the water for animals to breathe?
The lungs are the organs that "trap" oxygen from the atmosphere for animals to breath. Lungs do not really trap oxygen, however, they present a tissue to the oxygen-rich air in which the oxygen may diffuse into, where it can be captured by the hemoglobin in the blood.
When brought into an oxygen rich atmosphere steel will burn at what temperature?
Ignition temperature for of steel is normally around 800degC.
Why does earth need oxygen?
The oxygen in the air of earth is the result of biological processes over the past 4000 million years. Trees give out oxygen as they photosynthesize ------------------------------------------------------------------------------------------- Initially Earth's atmosphere did not contain free Oxygen (we know this from the chemistry of sediments that were first formed). Life on earth then happened and by the process of photosynthesis slowly began releasing Oxygen into the environment. At first this Oxygen reacted chemically with stuff (eg Iron salts) in the environment but over time all this "stuff" was converted and free Oxygen began to appear in the environment. This speeded up the development of life and about 600 million years ago there was enough Oxygen for life to use it to build calcareous shells and eventually for life to move onto the land. Thus life has made the planet we have today, Earth has been "terraformed" and now has an Oxygen rich atmosphere.
What was the affect that photosynthesizing had on the ancient atmosphere?
Early bacterial respiration in the ancient atmosphere (see the process of Photosynthesis photo1, and Photo 2 with oxygen waste product) released oxygen into the atmosphere leading to a oxygen rich atmosphere and the ability of other organisms that fix oxygen to evolve. i.e us! and animals.
What is the process of photosynthesis-?
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Here is a diagram.
What planet has a nitrogen- oxygen atmosphere?
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
What conditions characterize atmosphere III?
nitrogen-rich and oxygen-poor
Why does oxygen occur naturally?
It is a byproduct of the life processes on Earth. Earth's early atmosphere contained no Oxygen, but Earth was slowly Terra-formed by life and obtained an Oxygen rich atmosphere.
What changed your formerly poisonous atmosphere into an oxygen rich atmosphere?
well, the first ice age is when blocks of ice and rocks release oxygen which helps us breathe
Which process is the major source of oxygen released into the atmosphere?
Oxygen is made from photo-synthesis and is emitted by plants that use carbon dioxide from the atmosphere to extract carbon. Plants are made from carbon molecules, and sunlight falling on green leaves containing chlorophyll provides the energy to separate carbon from carbon dioxide.
What bacteria are thought to be responsible for establishing Earth's oxygen-rich atmosphere?
Cyanobacteria are believed to be responsible for establishing Earth's oxygen-rich atmosphere. Nearly 2.3 billion years ago, these microbes, which lived in the seas, were the first organisms to produce oxygen, leading to the transformation of the Earth's environment.
What planet has oxygon rich atmosphere?
Earth. It's the only planet with significant amounts of oxygen in the atmosphere, making up about 21%.
Plants release carbon dioxide during the whole night then how it is possible that morning atmosphere is fresh and rich with oxygen?
They give of oxygen
What happens to a copper rod if it is on fire?
Presumably burning in an oxygen-rich atmosphere, it is chemically reacting with oxygen to form copper oxide.
Which planets have oxygen rich atmosphere?
In our solar system there's only one and that's the Earth.
