The oxygen cycle is one of the main reasons for the existence of life on earth. … They release carbon dioxide as a by-product into the atmosphere and which is again used by plants.

Why is the oxygen cycle important to humans?

The carbon dioxide and oxygen cycle is critical to life on Earth. Humans and most other organisms need oxygen to survive. … That is why it is so important to help someone who cannot breathe by providing them with oxygen. Plants and other organisms that perform photosynthesis rely on animals for carbon dioxide.

How does the oxygen cycle affect the environment?

THE OXYGEN CYCLE allows for the regeneration of freely available diatomic oxygen (O2) in the atmosphere. Oxygen accounts by volume for approximately 21 percent of the atmosphere is reactive with myriad inorganic and organic substances and is vital to living organisms for aerobic respiration and energy production.

What is oxygen cycle explain?

oxygen cycle circulation of oxygen in various forms through nature. Free in the air and dissolved in water oxygen is second only to nitrogen in abundance among uncombined elements in the atmosphere. Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO2).

What is oxygen cycle in short answer?

Oxygen cycle refers to the movement of oxygen through the atmosphere (air) Biosphere (plants and animals) and the Lithosphere (the earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these regions as well as how it is used.

What is a very important part of the oxygen cycle?

Decomposition: It is one of the natural and most important processes in the oxygen cycle and occurs when an organism dies. The dead animal or plants decay into the ground and the organic matter along with the carbon oxygen water and other components are returned into the soil and air.

How human activities affect the oxygen cycle?

The two main human activities that affect the carbon-oxygen cycle are the burning of fossil fuels and the use and change of land. The burning of fossil fuels removes carbon from coal natural gas or other fuels and emits that carbon as CO2 into the atmosphere.

How does oxygen help in using up the food we eat?

Respiration is the process that allows us to breathe in oxygen and exhale carbon dioxide. Oxygen is then used in our cells as the fuel that transforms the food we eat into energy.”

How does the oxygen cycle affect the hydrosphere?

Over millions of years oxygen has become an integral part of our rocks and land. When water runs over rocks oxygen enters water. … Oxygen is also crucial in parts of the Earth known as the hydrosphere which is where any areas of water can be found both above the ground and under the Earth’s surface.

What are the uses of oxygen?

Common uses of oxygen include production of steel plastics and textiles brazing welding and cutting of steels and other metals rocket propellant oxygen therapy and life support systems in aircraft submarines spaceflight and diving.

What are the two important processes involved in oxygen carbon dioxide cycle?

Photosynthesis respiration and decomposition are processes that are responsible for maintaining the carbon dioxide–oxygen cycle. The process of photosynthesis in plants releases oxygen into the atmosphere.

Which would best keep the oxygen cycle stable?

Effective solution for keeping the oxygen cycle stable is replanting trees in deforested areas. This process is called reforestation. Reforestation can be done naturally (by natural seeding) or artificially (by direct seeding or planting).

What will happen to the Earth without oxygen?

Without oxygen there would not any fire and the combustion process in our vehicles would stop. … In between all this the earth’s crust which is made up of 45 per cent oxygen would completely crumble. It will crumble until nothing is left and send everyone on the planet into a free-fall.

Is one important human activity can decreases the oxygen levels present in the atmosphere?

Answer: cutting down of trees and burning of petroleum gases.

What is the effect of present oxygen?

In biochemistry the oxygen effect refers to a tendency for increased radiosensitivity of free living cells and organisms in the presence of oxygen than in anoxic or hypoxic conditions where the oxygen tension is less than 1% of atmospheric pressure (i.e. <1% of 101.3 kPa 760 mmHg or 760 torr).

Why is oxygen important to blood and to the cells answer?

Oxygen is important because it gives energy for our cells to work and not only the cells but also the cell organelles. By which the new systems of our brain and body gets opened our nerves which are blocked due to some reasons gets opened which helps faster blood circulation.

Why is oxygen important for all body cells?

Every cell in your body needs oxygen to function. … Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar.

What makes oxygen important during the respiration process?

Why is oxygen important? Oxygen is essential for respiration because the body uses it to ‘burn’ food molecules. Animals take in oxygen when inhaling and give off carbon dioxide when exhaling. Oxygen makes up almost 21% of the total gases in air with most of the remaining gas being physiologically inert nitrogen.

How is oxygen used up from the atmosphere and return back to the atmosphere?

Answer: Oxygen is returned to the atmosphere through photosynthesis.

What are 3 interesting facts about oxygen?

Here are 10 interesting facts about the element oxygen.
  • Animals and plants require oxygen for respiration. …
  • Oxygen gas is colorless odorless and tasteless. …
  • Liquid and solid oxygen is pale blue. …
  • Oxygen is a nonmetal. …
  • Oxygen gas normally is the divalent molecule O2. …
  • Oxygen supports combustion.

What are the importance of oxygen and carbon dioxide for living organisms?

Carbon dioxide (CO2) and oxygen (O2) are the most important gases for living organisms. CO2 is vital for use by plants in photosynthesis in which plants use CO2 and water to convert the Sun’s energy into food energy. This food energy is in the form of the sugar glucose (C6H12O6). Plants also produce O2.

Why is oxygen an important byproduct of photosynthesis?

In photosynthesis solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration oxygen is used to break down glucose releasing chemical energy and heat in the process.

What is the relationship between the oxygen cycle and carbon cycle?

Answer: They act separately but are dependent on each other because the carbon cycle gives off oxygen for the oxygen cycle to use and in turn the oxygen cycle emits carbon dioxide (CO2) which goes back into the carbon cycle. Plants are the main vehicle by which the oxygen and carbon cycles are connected.

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.

What keeps the oxygen cycle going?

Plants – Plants create the majority of the oxygen we breathe through a process called photosynthesis. In this process plants use carbon dioxide sunlight and water to create energy. In the process they also create oxygen which they release into the air.

How is oxygen replaced in the atmosphere?

the oxygen in the atmosphere is replaced by plants .

Is life possible without oxygen?

A team of scientists at the Tel Aviv University in Israel have found life-form that can survive without oxygen. … Some lower single-celled organisms or eukaryotes are able to respire without oxygen with a process known as anaerobic respiration.

Will the world run out of oxygen?

Yes sadly the Earth will eventually run out of oxygen — but not for a long time. According to New Scientist oxygen comprises about 21 percent of Earth’s atmosphere. That robust concentration allows for large and complex organisms to live and thrive on our planet.

What year will the sun explode?

Scientists have conducted a lot of researches and study to estimate that the Sun is not going to explode for another 5 to 7 billion years. When the Sun does cease to exist it will first expand in size and use up all the hydrogen present at its core and then eventually shrink down and become a dying star.

How important is oxygen in nature?

Oxygen plays a critical role in respiration the energy-producing chemistry that drives the metabolisms of most living things. … Oxygen is generated during photosynthesis by plants and many types of microbes. Plants both use oxygen (during respiration) and produce it (via photosynthesis).

What would happen if oxygen levels decreased?

If blood oxygen levels are too low your body may not work properly. Blood carries oxygen to the cells throughout your body to keep them healthy. Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases it can interfere with heart and brain function.

What are the reasons on the rise and decline of oxygen levels on Earth as years go by?

Oxygen levels are generally thought to have increased dramatically about 2.3 billion years ago. Photosynthesis by ancient bacteria may have produced oxygen before this time. However the oxygen reacted with iron and other substances on Earth so oxygen levels did not rise to begin with.

How is oxygen used in nature?

Oxygen is used by animals and plants in the respiration (breathing) process. Tanks of oxygen are used in medicine to treat people with breathing problems. They are also used as life support for astronauts and scuba divers.

Why is oxygen important in radiotherapy?

Much of this resistance is caused by the low levels of oxygen often found in tumors: oxygen is required for radiation therapy to generate the molecules called free radicals that kill cancer cells. When oxygen levels in a tumor are low radiation therapy is less effective.
