How is the oxygen in the atmosphere replaced or why does oxygen in atmosphere not get finished?
this is all because of plants and trees as they release oxygen during photosynthesis….the oxygen is replaced by human beings with carbon di oxide while the process of respirations. therefore oxygen is not getting totally used up..
How is oxygen in the air replaced Class 6?
Plants and animals use oxygen present in the air for respiration. Oxygen is also used for combustion. This oxygen is replaced by the plants during photosynthesis.
Who plays the main role in the replacement of oxygen in the atmosphere answer?
The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen.
Who play the main role in the replacement of oxygen in the atmosphere?
The waters of the world are the main oxygen generators of the biosphere; their algae are estimated to replace about 90 percent of all oxygen used.
How is oxygen in the atmosphere?
Early in our planet’s history, the atmosphere had almost no oxygen. Microbes that produce their food via photosynthesis generate oxygen as a by-product. Oxygen is generated during photosynthesis by plants and many types of microbes. Plants both use oxygen (during respiration) and produce it (via photosynthesis).
How is oxygen replenished in nature?
Oxygen is replenished or released in nature when green plants make the use of Carbon Dioxide to perform photosynthesis. During day time, atmosphere prevents most of the heat to pass through the earth’s surface. During night time, inversely, it prevents the radiation to escape through the earth’s surface.
How did the Earth get oxygen?
The modern atmosphere contains abundant oxygen, making it an oxidizing atmosphere. The rise in oxygen is attributed to photosynthesis by cyanobacteria, which are thought to have evolved as early as 3.5 billion years ago.
How is oxygen replenished in water?
Natural aeration It can occur through sub-surface aquatic plants. Through the natural process of photosynthesis, water plants release oxygen into the water providing it with the oxygen necessary for fish to live and aerobic bacteria to break down excess nutrients.
