The half-life of carbon-14 is the amount of time it takes for one-half of the original amount to disappear by radioactive decay.
This half-life is about 5,700 years and means that every 5,700 years the amount of carbon-14 in a fossil is only one-half of what it was 5,700 years ago.
Living plants are active components of the overall food chain.
Animals eat plants and/or other animals; humans eat plants and animals.
Carbon-14 will have all disappeared by radioactive decay.
When a radiocarbon dating lab doesn’t see any carbon-14 in a fossil, it knows the fossil is more than 50,000 years old.
Carbon-14 originates in the upper atmosphere of the earth and is created when neutrons originating from solar radiation bombardment collide with nitrogen in the air.
BETA has been the world leader in Carbon-14 analyses since 1979 and has unmatched expertise analyzing complex samples.

This principle applies equally to a person dying, a corn stalk being cut down, or to a soybean plant being pulled out of the ground.
When they stop living, they stop taking in carbon-14 from the air around them, and the amount of carbon-14 in the remains gradually disappears.
