Question

TRUE/FALSE. carbon-14 is constantly being produced in the upper atmosphere, and the amount is in equilibrium. as long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but at soon as it dies, it stops taking up new 14c, and so the geologic clock starts.

Answer 1

True. The amount of carbon-14 remains constant in equilibrium and is produced in the upper atmosphere.

Carbon-14 is a long-lived radioactive carbon isotope formed by the collision of neutrons and nitrogen atoms in the atmosphere when cosmic radiation occurs.

Organisms during their lifetime will absorb carbon-14, carbon-14 is a carbon that easily bonds with other atoms to help process reactions in the body. As in plants, carbon-14 acts as carbon dioxide, which is the raw material for photosynthesis. Carbon-14 is also decaying and the amount will be replaced when living things breathe and eat. The process of absorption of carbon-14 in living things will stop when these living things die, and the amount of carbon-14 in their bodies will decrease.
