Plants make oxygen and animals use oxygen. Over a couple of billions years, this system has stabilized so that oxygen makes up not quite 1/4 of the air you breath.
By far, the most oxygen-producing plants live in the oceans, and include algae, seaweed (See 'Sargasso Sea'), and other similar plants.
What else can I help you with?
How do plants and animals mantain the level of oxygen in the atmosphere?
Plants produce oxygen during photosynthesis by using sunlight to convert carbon dioxide and water into glucose and oxygen. Animals, including humans, consume oxygen during respiration to produce energy and release carbon dioxide. This continuous cycle of oxygen production by plants and consumption by animals helps maintain the levels of oxygen in the atmosphere.
An oxygen deficient atmosphere has an oxygen concentration less than?
An oxygen deficient atmosphere has an oxygen concentration less than the normal level of around 21%.
Why does the amount of oxygen in air not get depleted?
The amount of oxygen in the air does not get depleted because it is constantly being replenished through processes such as photosynthesis by plants and algae. These organisms convert carbon dioxide into oxygen, helping to maintain a relatively stable level of oxygen in the atmosphere.
How the amount of oxygen in the atmosphere affects respiration?
The amount of oxygen in the atmosphere directly affects the rate and efficiency of respiration in living organisms. Reduced oxygen levels can lead to decreased respiration and cellular energy production, resulting in physiological stress and potential harm to the organism. Conversely, sufficient oxygen enables efficient respiration, supporting metabolic processes and overall health.
What is the oxygen content of air?
The oxygen content of air is approximately 21%. Nitrogen is the largest component of air as it takes up 78% of the atmosphere.
How do plants and animals mantain the level of oxygen in the atmosphere?
Plants produce oxygen during photosynthesis by using sunlight to convert carbon dioxide and water into glucose and oxygen. Animals, including humans, consume oxygen during respiration to produce energy and release carbon dioxide. This continuous cycle of oxygen production by plants and consumption by animals helps maintain the levels of oxygen in the atmosphere.
How can you maintain oxygen in the atmosphere?
Well to maintain the oxygen in the earth atmosphere you need to make sure that the level of global warming is decreasing and less fumes will be able to make up the ozone layer. With a thinner layer around the earth this means that oxygen will be able to enter and exit the earths surface, allowing oxygen to still stay in the atmosphere.
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
What is the effect of sunlight on vegetable?
due to the present of sunlight photosynthesis is take place and its help to growth plant themselves and help to give oxygen to animals, maintain the oxygen level to environment.
An oxygen deficient atmosphere has an oxygen concentration less than?
An oxygen deficient atmosphere has an oxygen concentration less than the normal level of around 21%.
What is the Level of oxygen on Saturn?
There is oxygen in the atmosphere of Saturn, but it is only a tiny fraction of the deep atmosphere, which is mostly hydrogen. It is not in a usable form as is oxygen on Earth.
How often does oxygen cycle through the atmosphere?
oxygen is a constant 20 percent throughout the atmosphere. Even in space but the air is so thin in space that the oxygen would have to be compressed to be able to breathe it. Here on earth at sea level the atmospheric pressure is 14.7 pounds per square inch (PSI) making it possible for your body to inhale enough usable oxygen for you to breathe. As you go higher the pressure is less so even though the oxygen is still 20% of the atmosphere there is less atmosphere for you to breathe.
What 2 processes are responsible for keeping the percentage of atmospheric oxygen at a constant level?
Photosynthesis by plants and algae, and respiration by animals and other organisms help maintain the percentage of atmospheric oxygen at a relatively constant level. Photosynthesis consumes carbon dioxide and produces oxygen, while respiration does the opposite.
Why does the amount of oxygen in air not get depleted?
The amount of oxygen in the air does not get depleted because it is constantly being replenished through processes such as photosynthesis by plants and algae. These organisms convert carbon dioxide into oxygen, helping to maintain a relatively stable level of oxygen in the atmosphere.
How the amount of oxygen in the atmosphere affects respiration?
The amount of oxygen in the atmosphere directly affects the rate and efficiency of respiration in living organisms. Reduced oxygen levels can lead to decreased respiration and cellular energy production, resulting in physiological stress and potential harm to the organism. Conversely, sufficient oxygen enables efficient respiration, supporting metabolic processes and overall health.
What is the minimum amount of oxygen needed to sustain fire in the atmosphere?
The minimum amount of oxygen needed to sustain a fire in the atmosphere is about 16% oxygen. Below this level, the fire would not have enough oxygen to continue burning.
How long has the oxygen concentration of the atmosphere been at its current level?
The current oxygen concentration in the Earth's atmosphere has been relatively stable at around 21% for the past 300 million years. This level is maintained through processes like photosynthesis by plants and phytoplankton, which convert carbon dioxide into oxygen.
