What is the oxygen cycle in simple terms?

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.

How does the carbon dioxide oxygen cycle work?

The Oxygen-Carbon Dioxide Cycle

Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant’s leaves. … Even animals that live underwater need oxygen.

How many stages are there in oxygen cycle?

three stages

The oxygen cycle is the flow of oxygen molecules through these spheres. The flow of nitrogen oxygen carbon and water cycles in nature is essential for the sustainable development of the living components of the ecosystem. There are three stages involved in the oxygen cycle.

How do you explain oxygen to a child?

This element is colorless odorless and tasteless. That means even though oxygen is constantly around you you can’t see it smell it or taste it. What is this? Every time you take a breath you are breathing in oxygen and you need oxygen to live.

What is oxygen cycle explain with the help of a diagram?

The atmosphere contains about 21% oxygen.The atmospheric oxygen enters the living organisms as a gas required in respiration. During this process carbon dioxide and water are formed.

How does the oxygen cycle affect the atmosphere?

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.

How does the oxygen cycle affect the hydrosphere?

During the process of photosynthesis the hydrogen is combined with carbon atoms to produce oxygen which is then releases into the atmosphere. … 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.

Which of the following processes produces oxygen in the oxygen cycle?


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.

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 does oxygen occur in nature explain oxygen cycle in nature?

The oxygen from the atmosphere is used up by living organisms and then returned to the atmosphere again. The reservoirs where Oxygen is found are Atmosphere Hydrosphere Lithosphere and Biosphere. … 1) Plants undergo photosynthesis and release oxygen as a byproduct.

How do these processes explain the cycle of carbon dioxide and oxygen in nature?

When they’re exposed to light green plants use carbon dioxide from the atmosphere to manufacture living matter and release oxygen into the air. This process is called photosynthesis. Carbon dioxide is produced through the respiration of animals and plants which consume oxygen and release carbon dioxide.

What is biotic process of oxygen cycle?

In the process of respiration oxygen is taken in by living organisms and released into the atmosphere combined with carbon in the form of carbon dioxide. Carbon dioxide enters the carbon cycle or is taken up by plants for photosynthesis.

Where does oxygen come from?

At least half of Earth’s oxygen comes from the ocean.

Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants algae and some bacteria that can photosynthesize.

How do you explain oxygen?

Oxygen is a colourless odourless tasteless gas essential to living organisms being taken up by animals which convert it to carbon dioxide plants in turn utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere.

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 is a fun fact about oxygen?

Oxygen makes up around 21% of the Earth’s atmosphere. It makes up around 50% of the Earth’s crust making it the most common element in the Earth. Oxygen is also the third most abundant element in the universe and the most abundant element in the human body making up 65% of the body’s mass.

How air cycle occurs explain?

How does air cycle work? Air cycle refrigeration works on the reverse Brayton or Joule cycle. Air is compressed and then heat removed this air is then expanded to a lower temperature than before it was compressed. Work must be taken out of the air during the expansion otherwise the entropy would increase.

Which process helps in increasing oxygen in air?

Explanation: During the process of photosynthesis hydrogen is combined with carbon atoms to produce oxygen which is then released into the atmosphere.

What is biotic and abiotic processes in oxygen cycle?

oxygen cycle The cycling of oxygen between the biotic and abiotic components of the environment (see biogeochemical cycle). … In the process of respiration oxygen is taken in by living organisms and released into the atmosphere combined with carbon in the form of carbon dioxide.

How do plants release oxygen into the atmosphere?

Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

How does global warming affect the oxygen cycle?

The ocean is losing oxygen and global warming is largely to blame. As water temperatures rise oxygen solubility decreases and ocean stratification intensifies limiting both the amount of dissolved oxygen in the water and the supply of the gas mixed into deeper layers from the surface.

What is in the oxygen cycle?

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 the human impact on 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 is oxygen balanced in the atmosphere explain it?

Explanation: The oxygen in the air is used by the organisms present in the air water or soil or on earth for their respiration. … But green plants during photosynthesis use carbon dioxide of air for preparing food and they release oxygen gas in the air. Thus the balance of oxygen in the air is maintained.

How is oxygen released?

Oxygen Supply

Half of the world’s oxygen is produced via phytoplankton photosynthesis. The other half is produced via photosynthesis on land by trees shrubs grasses and other plants. As green plants die and fall to the ground or sink to the ocean floor a small fraction of their organic carbon is buried.

How does oxygen get in the air?

When you breathe in (inhale) air containing oxygen enters your windpipe passes through the bronchi and eventually reaches the air sacs. These air sacs called alveoli are responsible for gas exchange.

How do oxygen plants produce oxygen?

Plants make their food in a process called photosynthesis. … Once they have water and carbon dioxide they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

How is energy the driving force of the oxygen cycle?

Explain how the need for energy is the driving force of the oxygen cycle. The need for energy is the driving force of the oxygen cycle. … The main source of energy for Earth is the sun so if it continues to absorb large amounts of heat and emit less then the Earth’s average temperature will increase.

How do living things recycle oxygen in Earth’s atmosphere?

Explain how living things recycle oxygen in Earth’s atmosphere. Photosynthetic autotrophs release oxygen into the atmosphere when they make food through photosynthesis. All organisms both autotrophs and heterotrophs use oxygen from the atmosphere to break down glucose and make ATP during cellular respiration.
