What else can I help you with?
What is inferred to be the main source of the free oxygen that first entered earth?
oxygen producing organisms
Which group of organisms is the source of oxygen in the oxygen cycle?
Plants, algae, and cyanobacteria are the main producers of oxygen in the oxygen cycle through the process of photosynthesis. These organisms convert carbon dioxide and sunlight into oxygen and carbohydrates, sustaining the oxygen levels in the atmosphere.
What was first responsible for changing the formerly poisonous atmosphere to an oxygen-rich atmosphere have today?
The evolution of photosynthetic bacteria and later on, plants, was responsible for changing the formerly poisonous atmosphere to an oxygen-rich one we have today. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing levels of oxygen in the atmosphere.
What two products does photosynthesis create?
Photosynthesis creates glucose (a simple sugar) and oxygen as products. Glucose is a source of energy for plants, while oxygen is released into the atmosphere as a byproduct.
What was first responsible for changing the formerly poisonous atmosphere to am oxygen-rich atmosphere as we have today?
Early photosynthetic bacteria, such as cyanobacteria, were responsible for changing the formerly poisonous atmosphere to an oxygen-rich atmosphere through the process of photosynthesis. These organisms released oxygen as a byproduct of converting sunlight into energy, which gradually increased the atmospheric oxygen levels over time.
What is inferred to be the main source of the free oxygen that first entered earth?
oxygen producing organisms
What is inferred to be the main source of the free oxygen that first entered earth's atmosphere?
The main source of free oxygen that first entered Earth's atmosphere is believed to be the process of photosynthesis by ancient cyanobacteria, also known as blue-green algae, around 2.5 to 3.5 billion years ago. These microorganisms converted carbon dioxide and water into oxygen and organic compounds, gradually increasing the oxygen levels in the atmosphere.
What is the major source of oxygen for the earths atmosphere is?
Plants
What is the source of the oxygen that plants give off as oxygen gas?
The oxygen in water is the oxygen that is released into the atmosphere.
Which atmosphere gas is photosynthesis the major source of?
Oxygen is the major source of photosynthesis in the atmosphere. During photosynthesis, plants and other photosynthetic organisms convert carbon dioxide into oxygen through the process of photosynthesis. This oxygen is then released into the air, replenishing the levels in the atmosphere.
The primary source of oxygen for the earth's atmosphere?
The primary source of oxygen in Earth's atmosphere comes from photosynthesis by plants, algae, and some bacteria. During this process, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is then released into the atmosphere as a byproduct.
What is the major source of free oxygen in atmosphere?
Green Plants
What do you think is the source of oxygen in our atmosphere?
The source of oxygen in our atmosphere is primarily from photosynthesis, a process carried out by plants, algae, and some bacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for maintaining the oxygen levels in our atmosphere.
What is the source the ozone layer?
Oxygen in the atmosphere, and UV-C from the Sun.
What is hypothesized to be the early source of free oxygen in Earth's atmosphere?
cyanobacteria
What is the most source of oxygen for the earth atmosphere?
The most significant source of oxygen in Earth's atmosphere is photosynthesis by plants, algae, and cyanobacteria. These organisms take in carbon dioxide and water, using sunlight to produce oxygen as a byproduct. This process has been crucial in maintaining the balance of oxygen and carbon dioxide in our atmosphere for billions of years.
Plants depend on the atmosphere for the largest source of what?
Oxygen:) hope this helped Have a great day :) :p :D
