What is the source of the carbon that is used in radiocarbon dating in living things?
The radioactive isotope carbon-14 is natural.
What else can I help you with?
The carbon source for organisms that make their food from photosynthesis is?
the carbon source from photosynthesis is CO2 in the atmsphere. Carbon is the second most abundant element in living matter.
Is carbon dating valid or a lie?
Carbon dating is valid for:objects that were once living (had been in equilibrium with atmospheric carbon-14 levels)objects no older than about 40,000 years (still has detectable level of carbon-14)objects that are not fossilized (carbon has not been replaced)Carbon dating often has errors (due to variations in atmospheric carbon-14 levels over time), but these can be corrected by cross-referencing with tree ring dating.Some people want carbon dating to be wrong as it may contradict their strongly held beliefs, so in their mind it must be a lie. But beliefs can be wrong (even delusional), no matter how strongly held or the source they are based on.

What does NOT use an inorganic source of carbon as its sole source?
Animals do not use an inorganic source of carbon as their sole source. They obtain carbon from organic sources such as plants and other animals.
How does the original source of energy for all living things on earth get converted to a usable form for living things?
The original source of energy for all living things on earth is the sun. This energy is converted into a usable form for living things through the process of photosynthesis, in which plants and some other organisms absorb sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. Living things then utilize this glucose as a source of energy through cellular respiration.
What is the source of the carbon-14 that is used in radiocarbon dating in living organisms?
The source of carbon-14 used in radiocarbon dating in living organisms is cosmic rays from the sun interacting with nitrogen in the Earth's atmosphere, producing carbon-14.
In living things what is the source of the carbon14 that is used in radiocarbon dating?
Carbon atoms are contained in most cells of all living things on Earth. Most carbon atoms (98.89 percent) are called carbon-12 because they have 6 neutrons and 6 protons in their nuclei. Most of the remaining atoms (1.11 percent) have 7 neutrons along with their 6 protons and are called carbon-13 atoms, but a very small quantity (called a trace amount) of carbon atoms have 8 neutrons and 6 protons. These and are called carbon-14 atoms. Carbon-14 atoms are radioactive and are referred to as radiocarbon. They are unstable, and decay slowly by releasing electrons before evolving into nitrogen-14 atoms. A living organisms constantly absorbs carbon in its body systems by respiration and processing nutrients, and the amount of carbon-14 it contains remains fairly constant for as long as it lives. The carbon-14 decays without being replaced after the organism dies and half of the carbon-14 nuclei will disintegrate in about 5,730 years. The amount of carbon-14 that has disintegrated in a fossilized organism can be calculated and used for determining its age.
How does dendrochronology assist radiocarbon dating?
Tree rings provided truly known-age material needed to check the accuracy of radiocarbon dating as a method. During the late 1950s, several scientists (notably the Dutchman Hessel de Vries) were able to confirm the discrepancy between radiocarbon ages and calendar ages through results gathered from radiocarbon dating tree rings dated through dendrochronology. Today, tree rings are still used to calibrate radiocarbon determinations. Libraries of tree rings of different calendar ages are now available to provide records extending back over the last 11,000 years. Source: http://www.radiocarbon.eu/tree-ring-calibration.htm
What is the main source of living things?
The main source of living things is the break down of carbon. Carbon is essential to life. It is at the base of every organic compound.
The carbon source for organisms that make their food from photosynthesis is?
the carbon source from photosynthesis is CO2 in the atmsphere. Carbon is the second most abundant element in living matter.
What is the source of the most of the carbon?
The most important source of carbon entering atmosphere is industries. Living things, burning fossil fuels and automobiles are other sources of carbon dioxide.
What is the main source of energy for living thingsmade of the elements carbon hydrogen and oxygen?
the sun
What is the most important source of carbon entering atmosphere?
The most important source of carbon entering atmosphere is industries. Living things, burning fossil fuels and automobiles are other sources of carbon dioxide.
Is glucose a two carbon molecule?
No, glucose is a six-carbon molecule. It is a simple sugar that is a primary source of energy for living organisms.
What source of carbon takes the shortest time to form?
The source of carbon that takes the shortest time to form is biogenic carbon, which comes from living or recently deceased organisms. This carbon is constantly cycling through the ecosystem in processes like photosynthesis and respiration, making it a more dynamic and short-lived carbon source compared to fossil fuels or geological carbon.
Which is not a source of carbon dioxide gas?
Water (H2O) is not a source of carbon dioxide (CO2) gas. Carbon dioxide is primarily produced through combustion of fossil fuels, respiration by living organisms, and various industrial processes.
