Carbon-14 is a radioactive isotope of carbon that is naturally present in the atmosphere and is absorbed by plants during photosynthesis. As plants take in carbon dioxide from the air, they incorporate both stable carbon isotopes (like carbon-12) and the radioactive carbon-14 into their tissues. This process allows carbon-14 to enter the food chain, as animals and humans consume the plants. Over time, the decay of carbon-14 can be used for dating organic materials through radiocarbon dating.
What else can I help you with?
How and where is c-14 produced?
Carbon-14 (C-14) is produced in the atmosphere when cosmic rays interact with nitrogen atoms, transforming them into C-14. These C-14 atoms then combine with oxygen to form carbon dioxide, which enters the carbon cycle and is absorbed by plants through photosynthesis. Animals then consume these plants, thus incorporating C-14 into their tissues.
Where do plants get the minerals they need?
There are 14 essential plant nutrients. Carbon and oxygen are obtained from the atmosphere, and the other nutrients are absorbed from the soil.
When is carbon dioxide obsorbed day or night Why?
Carbon dioxide is absorbed by plants during the day through the process of photosynthesis. This is because plants use sunlight to convert carbon dioxide into sugars for growth and energy production. At night, plants respire and release some carbon dioxide back into the atmosphere.
How are carbon-14 isotopes formed?
Carbon-14 is produced in the upper atmosphere when cosmic rays produce thermalised neutrons, by hitting atomic nuclei. If these thermalised neutrons then hits a Nitrogen neuclei it creates Carbon 14.
What is exhaled by animals and absorbed by plants?
Animals, like humans, exhale carbon dioxide. Carbon dioxide is taken in by plants, and through the process of photosynthesis produce oxygen.

When carbon atoms are part of living material are carbon-14 isotopes absorbed on a regular basis?
Yes, carbon-14 isotopes are constantly being absorbed by living organisms through the food they eat or the air they breathe. Once an organism dies, it no longer takes in carbon-14, and the isotope starts to decay at a known rate, allowing scientists to use it for radiocarbon dating.
What gas do plants absorbed from the atmosphere?
carbon dioxide
What is carbon and oxygen cycle?
It is the process which the carbon is absorbed by plants and converted it to oxygen
What happens to carbon dioxide that is released by plants and animals?
The answer is: carbon dioxide that is released by animals is absorbed by plants ;)))
How does the plants gets the substances it needs for photosynthesis?
Plants need only two substances for photosynthesis, water and carbon dioxide. Water is absorbed from the soil (or from the water if they are acquatic plants) and carbon dioxide is absorbed from the air (or again, from the water if the plants grow underwater).
When is carbon dioxide obsorbed day or night Why?
Carbon dioxide is absorbed by plants during the day through the process of photosynthesis. This is because plants use sunlight to convert carbon dioxide into sugars for growth and energy production. At night, plants respire and release some carbon dioxide back into the atmosphere.

Carbon-14 is produced in the upper atmosphere when cosmic rays produce thermalised neutrons, by hitting atomic nuclei. If these thermalised neutrons then hits a Nitrogen neuclei it creates Carbon 14.
How carbon cycles in earth systems?
Carbon cycles in earth\'s system when it is excreted by animals, and then absorbed by plants.
Do living organisms all have the same ratio of carbon- 14 to stable carbon in their bodies Why or why not?
No, living organisms do not all have the same ratio of carbon-14 to stable carbon in their bodies. This is because the ratio of carbon-14 to stable carbon can vary based on factors such as the organism's diet, environment, and age. Carbon-14 is constantly decaying, so the ratio can change over time.
Which two substances do geologist use in radiocarbon dating?
Geologists use carbon-14, an isotope of carbon, and nitrogen-14 in radiocarbon dating. Carbon-14 is absorbed by all living organisms during their lifetime, and by measuring the ratio of carbon-14 to nitrogen-14 in a sample, geologists can determine its age.
