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.
Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO 2 ). CO 2 is then taken up by algae and terrestrial green plants and converted into carbohydrates during the process of photosynthesis, oxygen being a by-product .
Is photosynthesis part of the oxygen cycle?
In the biosphere, the main processes in the oxygen cycle are respiration and photosynthesis. During respiration animals and humans breathe by consuming oxygen to be used in the metabolic process and exhale carbon dioxide. Photosynthesis is the reverse of this process and is done by plants and plankton.
How does photosynthesis play a role in the carbon oxygen and water cycles?
Plants absorb carbon dioxide,water and sunlight to make their own food,grow and release oxygen through photosynthesis . They're a huge part in keeping our air clean. The carbon becomes part of the plant. ... When humans burn fossil fuels, most carbon enters the atmosphere as carbon dioxide.
Whats the process of photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy . During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What is oxygen cycle with diagram?
What is oxygen cycle explain with diagram? The cycle of oxygen describes the different forms in which oxygen is found and how it moves on Earth through various reservoirs . Three major oxygen reservoirs are present: the atmosphere, the biosphere, and the lithosphere.
What is the relationship between the carbon and the oxygen 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 carbon and oxygen form carbon dioxide?
Carbon dioxide: Carbon dioxide is a molecule composed of one carbon atom bonded to two oxygen atoms via two double bonds . Carbon dioxide is a byproduct of exhaling and from the burning of fossil fuels. Its natural existence is in the form of a gas, which is inert and non harmful to humans in very low concentrations.
Which two processes are involved in both the oxygen cycle and the carbon cycle?
In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism . During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
What is carbon cycle process?
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere . Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
What are oxygen cycles?
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 the oxygen cycle step by step?
- Photosynthesis :– During the day, plants take energy from the sun, carbon di oxide from the air, and water from the soil to make their food. ...
- Respiration :– The oxygen that is released by plants is used by humans, animals, and other organisms for respiration, i.e. breathing. ...
- Repeat :–
How does the water cycle relate to photosynthesis?
During photosynthesis, some excess water evaporates from the surface of the leaves, becoming water vapor . The water vapor in the process of transpiration travels into the atmosphere and becomes part of the water cycle, in the same way as evaporated water from lakes, rivers and oceans.
How do photosynthesis and cellular respiration work together to cycle carbon through an ecosystem?
Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules. Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration converts the organic carbon back into carbon dioxide gas.
What are the 7 steps of photosynthesis?
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent. ...
- Step 5-Light independent. ...
- Step 6-Light independent. ...
- calvin cycle.
What are the stages of photosynthesis in order?
| Stage Location Events | Light-dependent reactions Thylakoid membrane Light energy is captured by chloroplasts and stored as ATP | Calvin cycle Stroma ATP is used to create sugars that the plant will use to grow and live |

How do you explain photosynthesis to a child?
Photosynthesis is the process in which green plants use sunlight to make their own food . Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
How are carbon dioxide and oxygen recycled by respiration and photosynthesis?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis . While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Why is carbon dioxide and oxygen cycle is considered to be a cycle?
They are naturally present in the atmosphere in the form of carbon dioxide and gaseous oxygen. Because they're always circulating between the soil, the air, and the water, living matter's constantly renewed .
What is the difference between the carbon cycle and oxygen cycle?
Oxygen is needed for respiration, and carbon dioxide is emitted in the process . This inhaled oxygen is needed to produce energy (ATP) inside living cells from the process known as cellular respiration. On the other hand, carbon dioxide is utilized by plants for photosynthesis to produce carbohydrates.
What are the 4 steps of the carbon cycle?
Photosynthesis, Decomposition, Respiration and Combustion .
